Today our dryer started acting up. Sometimes it would start, others the light would just stay on sensing. We left it there for some time and it eventually started running. The next load it worked fine. Seems to be an off and on thing. Could it be a thermal fuse heating up ?

I have a Maytag Epic dryer that is suddenly not kicking on. I have power (tested for 120 on each side) the control panel works in all cycle settings. I ordered a thermal switch and thermistor from you guys and those haven't fixed the problem. When I push the start button (no matter what cycle setting) it beeps and the light by the sensing kicks on and nothing happens?? Thanks in advance!

Whirlpool Duet Steam Dryer is running but not heating. Model # WED9600TW0 1. Ran diagnostic tests 2. Receiving L2 “Low Line Voltage and F22 “Outlet Thermistor Open” 3. No breakers tripped, 240 measured at outlet, 240 at power cord connection 4. Ordered and replaced Dryer thermister after completing test 5. Still getting L2 and F31 6. Ordered and replaced Machine Control Electronics board after completing test 7. Still getting L2 and F31 8. Determined no continuity for the Thermal Cut-Off 9. Slammed on floor as shown on video and after second try getting continuity from the Thermal Cut-Off 10. No more L2 or F31 and dryer is heating once again 11. Dryer running and heating for short time 1 to 2 minutes then stops with flashing F22 12. Tested on different setting and same issue with F22 13. Watched Heater Element heat up go off and heat up again and at that point is when dryer stops and flashing F22 appears. 14. Went ahead and ordered the whirlpool-thermal-cut-off-kit 279973-ap3094323. Replaced both parts and tested again. Tested and still getting F22 as stated above (see #11,12, and 13). Need help with next steps needed. Thanks you in advance for your assistance.

Electric maytag dryer does heat and dry clothes but doesn't seem to get as hot as it used to, especially on high heat. Takes two cycles to dry clothes even on high. Vent looks clear and air blows out vent normally.

I have replaced the heater element because it was bad. It worked for about week then it quite heating clothes again. I checked it for continuity and its still good. I went ahead and checked the everything and the thermistor had no continuity so replacing that. I also checked high limit thermostat and that was good, but when I checked the thermal cut off fuse it had no continuity, so would that be the other problem? The dryer was heating and so I switched it over to time dry to take the cold out off the clothes and it didn't heat. I also set it back to heavy duty dry and still no heat. any recommendations would be great :)

This dryer started to run hot, and finally blew the thermo-fuse. I cleaned the vent tubes which were not blocked, installed a new thermo-fuse and it still runs hot. Even on air fluff setting I still get heat. I pulled out the element to see it it was grounded, and it looks and checked out fine. Where to next. Do I have a control board issue or am I missing something. Any help will be greatly appreciated.
