Broken contact on high limit thermostat - dryer no start
First I unplugged the dryer! Then unscrewed the two screws at the bottom of the front door. To remove the front door, swing the bottom up about 30 degrees until the two triangular hooks at the top of the door release. Then release the two wires going to the door switch from their harness so as to gain more slack to move the door out of the way. The switch was secured by 2 hex head sheet metal screws1/4inch in diameter. I used a small right angle socket wrench to get these loose. I only had to remove the front screw completely to be able to take the switch out for exchange purposes. Once this was done, reverse the process and plug it in! (BTW, the electrical schematic for this dryer is up under the top console)

Dryer would dry for 5-10 minuets then no heat
I tested the dryer coils and found that they were getting a voltage but would not open the gas valve. Coils were not bad but weak. After they warmed up they would not open the gas valve. It took 10 min to repace both coils and the heat sensor.

Dryer would not heat up.
I unplugged the dryer,removed the two small screws on the front of the dryer and pulled the bottom forward. The two wires connected to the door do not have to be removed. With an electrical tester using the Ohm setting I tested the Radiant sensor and the Gas Valve coils. The two terminal coil was DOA. The dryer can be operated with the front open as long as the door wires are connected. Symptons: The igniter would heat up and not release gas. My repair was successfull due to this awesome website and the super fast shipping service. AAAA++++

No Heat In the Dryer.
Let me give a little background first for those trying to diagnose their dryer issue. My dryer was turning on and running but the clothes were not drying. From everything i read I thought it was going to just be the IGNITER (part# 304970 [Partselect# PS373025]), but when I opened the dryer and watched it worked I saw that the igniter was working fine and the gas was coming on. This made me think that it is was the HIGH LIMIT THERMOSTAT (# 3033950 [Partselect# PS2029366]). I replaced this and got no real change other than the gas would stay on a bit longer at the start. So I replaced the other TEMPERATURE CONTROL THERMISTOR (# 3072080 [Partselect# PS2030068]) but this had no effect. I then went back to my original thought of the igniter and replaced it with no improvement. My dryer was still running and only occasionally lighting the gas to heat up the drum, the clothes would eventually dry after a much longer than normal time. After reading some other stories I decided to try the GAS VALVE WITH COILS. I ordered the part and was surprised when it arrived at my house the next day. I took out the four screws in the front panel which are accessed by opening the door to the dryer. I shut off the gas and removed the igniter to avoid any accidents with it. Unscrew the gas line from the old valve, remove two screws in bottom of unit to remove it from the dryer. Turn it over and remove two small screws to remove old valve from housing. Now take your new valve and do the opposite. Set in the housing, screw in the two small screws, place in dryer and replace two screws to hold in place. Screw gas line onto new valve and replace igniter. Turn on the gas and give it a test run. My dryer fired right and for the first time in a long time the whole dryer actually got warm.

Dryer stopped working
From previous experience I suspected the thermal fuse. Turned off the power and removed the front of the dryer by removing the two philips head screws in the door hinge and the two screws on the opposite side of the opening. The front came off easily since all that holds it in place besides the 4 screws are two spring clips. The thermal fuse is located on the side of the chamber enclosing the heating element. I removed the wires connected to the thermal fuse and temporarily joined them together with a spade type connector in order to determine if the thermal fuse was the problem. Turned the power back on and tried the dryer......it ran normally. Turned the power back off and removed the thermal fuse by taking out th two screws with a 1/4" nutdriver.
Ordered a replacement thermal fuse, installed it (with power turned off) and put everything back together. Dryer functioned normally after the thermal fuse had been replaced.
The thermal fuse can be removed and reinstalled using a 1/4" nutdriver. The wires are connected with push on spade type terminals.
Note: The swing damper on the dryer vent (the hooded cover where it exhausts to the outdoors) was jammed in the closed position with an accumulation of lint, which caused the dryer to overheat and blow the thermal fuse. If you experience a blown thermal fuse, always look for the cause or you'll blow the replacement within minutes of running the fryer again.

baffle broke off and needed to be replaced
we replaced the baffle by removing the broken baffle. There were two screws holding it in place. Door and front panel of dryer had to be removed to accomplish this task. Quite an easy repair/replacement. Thank you for all your help PartSelect.com.

Dyer would not heat, flame would shut off within 10 seconds
I opened the panel, undid the plugs, detached the radiant sensor by undoing one screw and removed and replaced the part. Fairly simply.

the dryer was just getting warm at best
The dryer was not getting hot the clothes we're damp and had to put on hangers to finish drying. I pulled the cover plate saw the element was glowing the gas cable would kick on had a flame for about a four to six second count. I did some checking on the web. I read about others who were having same type of problem. Order the limit part and now.the flame stays on for about twenty second or less the dryer gets hot and it drys fast. Thanks for the web site. It took about thirty minutes . Now it works great.

Brand new dryer...needed to convert to propane.
I followed the directions that came with the conversion kit; which I ordered from PartSelect. Your website was the only place that could help me. Our new dryer is actually a Samsung. The people at Best Buy were no help. I called the Samsung headquarters and a "real" person there told me I could order from them or use a Whirlpool kit because they are the same. You guys were faster in getting me one, so I went with you. My wife was happy. I would recommend you to others.

Dryer Timer Not Working - Timer Dial Skirt Broke
I ordered a new timer skirt and also a new timer knob(only to be safe) and they arrived the next day! I watched the instruction video on your website and it showed me how to take apart the skirt knob and cover. It was so easy. I reassembled the three parts which took about 2 minutes and put it back on the silver post that holds the timer dial. It worked as good as new. My husband was proud of me. I have recommended your website to my friends.

Rattling sound.
Turned off circuit breaker. Removed two screws at base of front panel with stubby Phillips-head screwdriver. Swung panel up about 30-degrees, and removed panel, disconnecting red and yellow wire to door switch. Removed four sheet metal screws and took off large drum support bracket. Checked drum support rollers and shafts. They were fine. Reset circuit breaker and turned on dryer. Rattling noise still present.
Removed six small screws holding blower fan assembly. Shaft receiver on squirrel cage fan was worn completely round (it should fit onto a half-round shaft). Ordered new blower fan from PartSelect.com. Replaced tonight, and it works beautifully. This dryer is 29-years old. All it's ever needed in the 10-years I've owned it is a belt replacement and this repair. Long live the 1970s Maytags, and good parts suppliers like this one.

Would not heat sometimes
Pulled the big front panel by removing two screws near bottom of front and pulling out at bottom until the top pops loose. Vacuumed out all of the dust and checked for loose connections. Ran dryer - igniter would light, but no gas. Checked the two solenoids with a VOM. the one with the two leads would intermittently read Infinity (open). Super simple repair. Remove two screws on solenoid bracket on top of the gas valve, Replace solenoid and plug it back in with the easy push-on connector. NO PROBLEM - all fixed.

Dryer was making awful noise during use
Removed the screws and took the door off then took the front panel off and popped up the top. Then pulled the drum out. Took snap ring pliers and removed rollers and replaced with new rollers then vacuumed all lint from machine and reversed operation to put everything back together. Operation was a total success!

Gas dryer runs, but no heat.
Unplug the dryer and remove the front panel (two screws at bottom of the panel), being careful of the door switch wires attached to the front panel. Using an ohm meter, I checked the ignitor for continuity and found it was open (should be 50-100 ohms). Make sure to check the solenoids on the gas valve. When the igniter goes bad, it will usually burn out the valve 1 solenoid boost coil (the one with 3 terminals), which was the case with my dryer. The solenoid coils are held in by a bracket with two screws (series 01 dryer) and are easy to remove and replace. Be careful replacing the igniter as the heating element is VERY fragile. Take the time to vacuum out all of the accumulated lint and dust inside the dryer while the front panel is removed, including the lint trap and duct. New igniter and boost/hold solenoid fixed the problem.

Dryer made very loud squealing, screeching noise. (Sometimes Intermittent, sometimes constant)
Note: You may want to consider replacing the 2 Drum Support rollers at this time (while your in there)

1. UNPLUG YOUR DRYER FIRST.

2. Using a phillips head screw driver - Remove 2 screws that secure the dryer door hinges to the frame, Lift door very slightly to unhook hinges and pull out door with hinges attached as straight as possible, set aside. Remove the 2 plastic tabs from the opposing side of the door hinge also secured by screws.

3. Remove the front panel (panel is shaped like a football goal post) by tilting out the top ends of the front panel toward you, then lift up to remove panel from the bottom metal retaining tabs.

4. Remove the 2 hexhead screws from the 2 retaining clips (security hooks) that secure the top
of the dryer closed.

5. Systematically remove the hexhead screws from the rest of the front of "shroud" (it holds (suspends) the drum in place between the front and back of the dryer).

*** I didn't disconnect any wires, I carefully swung out each piece that had wires attached, propped up those parts vertically ensuring no strain on the attached wires. Others may want to disconnect wires to avoid breaking or damaging them.

6. Vacuum out any dust/lint that may be present.

7. Draw a quick diagram of how the underside of the belt is threaded on the idler pulley and motor pully first. Release the tension of the belt from the underside of the drum. The easiest way is to push the idler pulley arm away from the belt and slide off the belt from the idler pulley and motor pulley. Slide the drum out.

8. Remove the hexhead screw from the bottom of the idler arm. Disconnect from retaining spring.

9. You may only need to replace just the Idler Pulley Wheel. I recommend replacing as a "unit" the Idler Pulley Wheel, Idler Arm, Ring-E and Idler Shaft Washer(s) - then you can just swap out the old one for the new one.

10. Reassemble

(When reassembling the belt - place around drum first and slide drum in place. Now from the underside-place (drape) belt around the motor pulley (it will be very loose) Now push the idler pulley arm toward the motor pulley, engage the left side of the belt around the idler pulley and slowly allow idler pulley to increase its tension on the belt) You can test manually by rotating the drum by hand to ensure proper movement.)
