Parts That Fix Whirlpool Washer Dryer Combo WET4124HW0 Drum Not Spinning
This part provides the tension required for a multi-ribbed belt. It also helps the belt rotate the drum and attaches to the idler pulley wheel. If your dryer will not start or tumble, takes too long to dry, or is noisy during operation, you may need to replace the idler pulley assembly. Make sure to disconnect power before installing this part, and wear work gloves to protect your hands. While the dryer is disassembled for this repair, consider replacing the drive belt as well. You will need a putty knife, a Phillips screwdriver, and a 5/16 nut driver for this repair.
The drum support roller kit allows the dryer to tumble properly by supporting the drum cylinder. The kit includes two drum rollers, four tri-rings, and one palnut (or retaining washer). The kit does not include a belt or idler pulley and rollers are not sold individually. The drum support roller kit may need to be replaced if the dryer is noisy or will not tumble. The tools needed to complete this repair are a putty knife, Phillips screw driver, and a 5/16 nut driver. This is an OEM part sourced directly from the manufacturer.
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.
