HI. There are a few areas i would advise to check to resolve this issue.

The dryer uses multiple thermostats to regulate the temperature. When the temperature is higher than the preset limit of a particular thermostat, the thermostat breaks the circuit and the heater goes off. When the temperature cools enough, the thermostat closes the circuit again and the heat can come on.

Most dryers have a choice of temperature settings, therefore a separate thermostat is used for each setting. The selector switch or timer control then routes the circuit through the appropriate thermostat.

If a thermostat fails, it may prevent the heat from coming on, This happens because the thermostat does not close the circuit when the temperature falls below the operating temperature of the switch. It is a simple matter to test a thermostat; it should show continuity when the switch is cool and no continuity when it is warmer than its rated temperature.

A thermostat can also fail by being always on, no matter what the temperature. This switch would show continuity whether it was hot or cold. In this case, the heater would not shut off and the the dryer could dangerously overheat. As a safety precaution a second thermostat is used, This is called a thermal fuse. The power will be cut to the heating circuit if the maximum safe temperature is exceeded. In most cases, this is a one time fuse. The heater circuit will not function until the fuse has been replaced. Of course, it will be necessary to determine and repair the underlying cause of overheating or the fuse will just cut out again. The most common cause of overheating will be a clogged ventilation assembly. Be sure to inspect the entire ventilation assembly for build up. This will cause issues, if obstructions exist.

The thermostats are usually grouped together. The are typically oval in shape and about an inch and a half in size. They may be on the blower housing, under the lint trap or inside the vent line. There should be two wires connected to each thermostat.

Label the wires and connections so that you can properly reconnect them later. The wires are connected with slip on connectors. Firmly pull the connectors off of the terminals. You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If either is corroded they should be cleaned or replaced.

To test the thermostats or fuse, set the multimeter to the ohms setting X1. Touch one probe to each terminal. You should get a reading of either zero or infinity. At room temperature, the thermostats should have a reading of zero. When the thermostats are heated to their limit temperature, they should switch off and you should get a reading of infinity. The fuse should be tested at room temperature for continuity.

NOTE(If the Thermostats and fuse check out ok, replace the element. Element failure is uncommon but, it may fail in certain cases))

Lg dryer is overheating blowing the thermal fuse


you have an airflow problem. Check the vent hose all the way out and the outdoor vent hood.
a simple verification can be performed by disconnecting the vent hose from the dryer and see if this solves the problem.

I have a Whirlpool Gold ultimate Care heavy duty Super Capacity Plus. Model: CEQ8858EQO & Serial number: MH1503498. It overheats when it hits the 'cool down' mode, or 'air fluff',...


Hello Gregory,

Their are 2 things that will typically cause that

1) the venting is crushed/blocked/restricted,check the vent from the back of dryer all the way to where it exits outdoors

2) i can not find your exact model number so i dont kow if it has a computer control or simple timer
if computer control the thermister(electronic thermostat) is what i would suspect
if simply timer the cycling thermostat is in question

So ya know the thermal fuse is a non resettable fuse and if were bad the entire dryer would not start so disregard it as beig the trouble uless the dryer doesn't run

My electric dryer is becoming extremely hot during the drying cycle. I replaced a blown thermal fuse several weeks ago and the dryer was extremely hot at that time. The dryer runs but becomes so hot you...


Clothes will get very hot in the dry cycle, especially when the dryer is set to the warmest or hottest setting.
There are controls built into the unit to prevent it from overheating to the point of causing a fire. The thermal fuse you replaced is one of them (and I assume you replaced a perfectly good fuse with a new one as you said it was very hot.).
You might want to check the following if you feel the unit is getting too hot -

1) Make sure the lint screen is clean.
2) Make sure the hose between the back of the dryer and the exhaust duct at the wall wall is not kinked or full of lint.
3) Make sure the exhaust duct leading to outside of the house is clear and not full of lint.

Let me know what you find.

Whirlpool gold side by side is thawing out and won't stay cold


The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can’t flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad it can prevent the heater from coming on OR it won’t turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it’s bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it’s in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others.

Not Cooling


The defrost heater and compressor can't operate at the same time unless the timer is bad. It disconnects the compressor and evap. fan during defrost cycle. Not sure what you call the "fuse", are you talking about the clip on disk that's on the evap. coil? If so that is the safety "fuse" as you call it to "open" and kill power to the heating element if the element gets the interior too hot. Usually water seeps in then freezes and pops the expoxy plug up thus breaking the normally closed power loop. If you have power going to the heating element (and it's hot, etc.) AND the fan/compressor is running then it has to be the defrost timer that's bad. There's just no way the heater element can be getting power at the same time the compressor is getting power unless that timer is bad (or a major short in some wiring somewhere). If you unplug the timer what effect does it have on your system? Let us know, this one sounds interesting...
