Dryer kept throwing the E1 error indicating the thermistor needed replacement
Unplugged the Dryer first. Removed the two screws from the bottom panel using a 1/4 socket and removed the panel by pulling down and out. Reached behind the blower and removed the connectors from the old thermistor and then the thermistor itself by removing the two 1/4 inch hex head screws. Replaced with new part and after screwing back in, reconnected the wires and replaced the panel. From start to finish, it took me about 20 minutes.
I researched causes of the noise, zeroed it down to the idler pulley. I then got the dryer schematic and took the dryer apart after disconnecting the power and the vent. i did not have to remove the drum, the idler pulley was easily accessible once the top and back panels were removed. I simply removed the drive belt from tension off the pulley, removed the old pulley and installed the new one. Once finished the dryer was running whisper quiet.
I started by changing the part that had the highest percentage to solve this problem , the top three didn't work , the fourth part, the disposable thermostat, and the last one that could be done from the front worked.
I removed the top first followed along with removing the side bracket that holds the circuit board. I then proceeded with removing the bottom cover and front panel. I disconnected the front panel from the control board and was able to slide the front panel upward. The door and blower housing was a bit tricky to pull out without thinking I was damaging something. I then replaced all the seals and cleaned the dryer after removing the drum and belt. I also replaced the drum support rollers. Afterwards I put everything back together and had an "E1" error and I pulled the thermostat out and wiped it down from all the lint and dryer worked perfect after that. Dryer takes the right amount of time to day clothes and no more rumbling noise. The instructions videos were VERY helpful.
I googled the problem and determined that the thermistor was faulty. I found your web site from which I ordered the replacement part. The part arrived within a week. The replacement was not particularly difficult, but the space was very tight (without removing more panels and covers). I just kept at it and got it installed and the dryer works fine now. There are several pertinent videos on you tube, none of which were my particular model, but the combination of them led me to a successful installation.
The hardest part was figuring out how to access the dryer mechanism. This Amana dryer has a lower front panel that is removed and not the top. There are few instructions available for this configuration. Then the part locations do not resemble the video instructions for trouble shooting. I discovered the broken part because when fiddling with the wire connections the metal tab disconnected due to fatigue or corrosion. Removing, identifying and replacing the flame sensor was quite simple. The dryer now works as before. The dryer is 23 years old. The most time in this repair was spent figuring out how to disassemble and identify a different configuration than in the videos.
I thought it had to be the igniter so I replaced that part. The dryer still did not start. I replaced the high limit and hoorah dryer works. Two weeks go by, the dryer is drying the clothes but my wife smells gas in the laundry room. I replaced the coil pak on the gas valve. My wife says she still smells gas. I replaced the radiant flame sensor and no gas smell for 2 weeks now.
Checked fuse with Volmeter, had continuity (acted as a short) not the problem. Disconnected Hot Surface Igniter 2 Position connector to check resistance for a range of 50-300 Ohms of resistance with Voltohm Meter. Meter read open (High Resistance). Removed Igniter by unscrewing 5/16" hex nut on igniter plate assembly and noticed silicon carbide element was cracked in the middle. Ordered a new igniter and noticed assembly was required. Be careful here as igniter element is fragile, also do not touch it with your bare hands. You have to lay down on floor to reinstall igniter assembly and you might want to practice anchoring the defective igniter to gain confidence. Finally with slow movements anchored new igniter assembly and turned on dryer. Watched igniter glow heating gas valve and heating gas flame returned. Dryer fixed for a few hours of study online and cost only $24, plus learned how the gas dryer works.
Unplug unit turn off gas, remove only bottom front panel first tried radient flame sensor was not the problem it was the coils which were infront easy to acess with small screw driver remove two prong coil and replaced then the three pronged coil being sure to line them back before tigtening left off cover and watched for ignition once it turned on and ran replaced cover and done.
Very easy repair... The video was really helpful too. I was able to find a different video that was closer to our model. (Front Loader HE) It probably took me a little longer than needed but I took the time to shop-vac everywhere I could, since it was all easy to get to. I opted for next day shipping so the shipping charges were more than the part. Tools I used were: Cordless drill-screw driver, 1/4in. socket, Phillips head bit and needle nose pliers for the control panel connections. Thank you again for making this so easy. Saved us a lot money by not calling an appliance repair tech.
Watched instructions, Ordered the kit and repair was fairly easy until the time to line up the cover over the fan wheel. That was difficult part. Would be best to have two people at this point to hold it and align the screw holes. Otherwise its was a fairly easy operation.
Turn off electric to unit. Remove lint trap. Remove lower cover below dryer door. 1 grey clip on either side. Bend upper portion of the clip down while pulling forward on panel. Remove 4 1/4 inch bolts that hold blower duct to fan. Push pulley upward while removing belt. Use a small angled pick to remove pulley lock ring. Install new washer and pulley. I added grease to pulley shaft. Hope this helped. Good luck
Message indicated something amiss in the motor circuit. Followed Instructions in the on-board manual. Turned out to be the internal-bias thermostat, and the exhaust air thermistor both. Changed faulty parts, cleaned lint from the system and we are off and running again. Thank You. DW Pranger
Removed the top, front cover, drum and belt. Removed the idler pulley bracket and pressed the frozen pulley from the shaft. Cleaned the shaft and applied a small dab of anti seize and replaced the pulley. Installed all parts in reverse order. Dryer works like new again.
