Hi-Limit Thermostat

Mike for Model Number Amana Dryer Model #NED7200TW

Answer Hello Mike. You need to test the thermistor. Component Electrical Testing (with ohmmeter) • Thermistor resistance 10K O @ 25°C 77°F PTC (2P-Blue & Red wire) • Thermostat 1 resistance < 1O (White & Yellow wire) You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html 

Tracy for Model Number MDE2706AYW

Answer Hello Tracy, This is most likely the thermal fuse 40113801. It can also be the heating element Y503978 or the high limit thermostat W10116735. These are bad to burn a wire so you should probably look for that. These are rather sensitive to excessive temperature, so it isn't a bad idea to check the exhaust ducting to prevent a repeat of the same issue. The exhaust is more important than most will give it. If the air flow is restricted the heat, lint, and moisture will simply blow past the felt seals, back into the cabinet with all of your heat and moisture sensitive electrical devices. The thermal fuse is just that........thermal. This means that it is opened by temperature. If it is open, which is what the issue most likely is, it was caused by the exhaust not allowing the heat, lint, and moisture to exit the unit. As per all of the manufacturers, flexible ducting is not recommended. It tends to get crimped and clogged too easily and causes customers to think that the dryer is "a piece of junk". In actuality, the most important part of the dryer isn't even part of the dryer. It's the exhaust duct! If you replace the thermal fuse without correcting the exhaust duct, the thermal fuse will most likely just blow again. 

Bob for Model Number ALE443RAW

Answer Hello Bob. Test the temperature with a meter. It should rise to around 160°, then start coming down. If not, the cycling thermostat may need to be replaced on the unit.

Answer G, You forgot to attach a model number. but, in general, there other things to check or replace. With the new venting, and you're sure there are no kinks or restrictions and the vent hood is not too close to the ground or collapsed, you'll need to first check for and remove any lint build up in the air duct assembly and blower housing 37001141, check and make sure the blower wheel 56000 and vanes are clean, not cracked and the wheel fits tight on the motor shaft. and there are no air leaks around either drum seal, and blower inlet seal. This time, repalce both the thermal fuse 40113801 and high limit switch W10116735 at the same time. 

Mick for Model Number mde308dayw

Answer Hi Mick. Start by replacing the timer part # 37001251. Make sure your sensor bars below the lint screen inlet are scuffed off w/scotch brite pad. This will allow the clothes to pass over them and be sensed better. Make sure you have the proper 240 vac to the terminal block and 120 vac from each end leg(blk and red wire) to the center white wire (neutral) wire. Make sure the connections are tight. Make sure your temperature selector is positioned correctly part # 37001164. Let us know if we can help further once these all have been checked. If the timer is sticking then you need to start there as it may just repair all. Thank You.

Answer Hello Thunder. The wire could have been damamged from a clogged or kinked vent assembly 37001148 is the wiring harness for the unit. Hope this helps.
