Parts That Fix Whirlpool Dryer 7MWGD1900EW1 Not Heating

The Dryer Thermal Fuse (Thermal Cutoff, Temperature Fuse) is a 2 by ½ inch, white, plastic safety mechanism that stops the flow of electricity to the motor circuit when a dryer overheats. If the fuse is missing or broken, your dryer will not start. A thermal fuse fails when the exhaust temperature exceeds the fuse rating, that is when the temperature rises above the temperature that the fuse is designed to handle. This can occur when a heating element is shorted, a regulating thermostat or thermister fails, or with a partially restricted exhaust vent. The fuse attaches to the blower wheel housing. It must be replaced when there is no longer continuity between the terminals. This is a one-time fuse, meaning it cannot be re-set. The replacement part features two 3/16 inch terminals.

If your dryer will not heat, takes too long to dry, or does not provide enough heat, you might want to replace your igniter kit. This silicone carbide igniter with ceramic holder kit includes the 3-inch flat igniter, bracket, 4-inch wire leads, and the plug. The kit can replace both round and flat igniters and is used for many gas clothes dryers. Be sure to disconnect the power source from your dryer before you do this repair. The igniter is located within the burner assembly, so you will require tools to complete the repair. You will need a putty knife, a small flat blade screwdriver, a 5/16 nut driver, and a 5/16 socket with a ratchet.

If your gas dryer is not heating up or igniting, then replacing the flame sensor, located in the burner assembly, could solve it. This part senses heat from the igniter to monitor if it is hot enough to ignite gas to light the burner. Once the igniter is hot enough it will open the valve and allow gas to flow. This is a safety mechanism to prevent dangerous levels of gas from building up. To repair, the main top of the dryer should be lifted, as well as the front panel to access the component. This flame sensor assembly is made of both plastic and metal.

This OEM high-limit thermostat kit includes the thermal cut-off fuse and the high-limit thermostat. The purpose of this part is to cut-off power to the dryer when it overheats. Common indications that this part requires replacement are if your dryer will not start, it is overheating, or no heat is coming from the dryer at all. Please note that the manufacturer has made updates to this part so it may look different from the original.

This thermostat has an internal heater L155-25F. This thermostat controls the internal drying temperature.

This dryer drum belt (Whirlpool Dryer Belt, Drive Belt) has four ridges, three grooves and is 1/4" wide, and 92 1/4 inches in length. It comes in black and is made of rubber. The belt transfers the rotation of the motor to turn the drum. The belt attaches to the drum, idler pulley, and motor pulley.
