Customer Questions and Answers for Dryer Thermal Cut-Off Kit by Whirlpool

Dale, The thermal fuse in located on the heater element housing. You need to unplug the power cord or remove power to the dryer, Remove the two hex-head screws from the bottom flange of the toe panel. Pull the panel out at the bottom, pull down, and remove the panel. You will now have access to the housing and the fuse. There are no specialty tools needed,other than 1/4 in sockets and wrench or nut drivers, Thanks and Good Luck

Hello Anthony. Based on the error code, it sounds like the thermistor WP8577274 is bad and will need to be replaced. Hope this helps.

Hi Daniel. Yes the hi-limit is bad part # WP3391914, along with the heater needs to be checked to see if it is not shorted against the chassis allowing it to overheat. Heater part # WP3387747. The Dryer thermistor needs to be ohmed out to see at room temperature (77°) it is 10,000 ohms. It senses the temperature to the main control board. It is part # WP8577274. Clean your vent entirely and make sure the outside vent cap is operating correctly not allowing the outside moisture not to get back in. Thank You.

Leonard, Did you check the heating element resistance (7.5 to 12 O ) to see if it has damage ? Based on your information, the thermal fuse and cut out are OK. You also need to check the breakers in the breaker box, they should be rated at 30 amps 240 VAC. The 5.6 amps it draws at present, should not be causing the breaker to get hot and trip open, unless theres an issue with the wiring or breaker. Thanks and Good Luck

Hello Perry. Yes, you can remove the screw in front of the heater box, and pull the heater box forward and remove it from the dryer. Now you can access and replace the thermal cut-off 279973. Reinstall in reverse order. Hope this helps.

Hello Perry. You will need to check the thermal fuse WP3392519 and the door switch WPW10318609. They should read closed for continuity with the door closed on the door switch. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Hi Marco. Is your dryer giving just the audible beep or is it giving a fault code? You are really having a vent issue resulting in other symptoms.It sounds like the venting system is clogged or kinked. You will need to check the vent and clean it out. Be sure and clean the vent pipe and the dryer air duct assembly. If the air flow is not good, the unit will retain moist air causing the clothes not to dry. Try running the unit with the vent unhooked from the back of the dryer and see if the dryer works properly. The thermistor will act as a cycling thermostat in by telling the main control board cut in and cut out temps.Thermistor Temperature Resistance 77°F..................10,000 ohms 36°F..................29,500 ohms 0°F....................86,300 ohms This part # is WP8577274. 2).= The thermal fuse will open and stop all heat. This part # is WP8577274.The thermostat part # is 279973. Also use a kitchen scrubber pad on the sensor 2-side by side bars to remove the fabric softener sheet build up. this will stop sensor readings to the sensor dry control board. Thank you.

Marco, No there are no "special" tools required to replace the thermostat, basic hand tools will work for you. Once you remove the lower access panel, you'll be able to access, test and replace the parts as needed. Good Luck.
