Estate dryers
All dryers →Replace the dryer drum rollers and idler pulley (Whirlpool-built 29 in)
On the common Whirlpool-built 29 in dryer, two rear rollers and the idler pulley wear together. Replace both rollers, the idler and the belt as a set (kits exist for this platform). The drum must come out: open the top, remove the front panel, release the belt from the idler, lift the drum out, then swap the parts on the rear bulkhead.
Replace the thermal fuse and cycling thermostat (electric dryer, Whirlpool-built rear access)
On Whirlpool-built electric dryers the thermal fuse and cycling thermostat mount on the blower housing behind the rear panel. A blown fuse is a symptom: always find the cause (vent restriction, stuck cycling thermostat, grounded element) and replace the cycling thermostat when it is suspect. Swap both parts one wire at a time, clean the blower area, and verify airflow before leaving.
Replace the electric dryer heating element (Whirlpool-built rear access)
On many Whirlpool-built electric dryers the element sits in a sheet-metal canister behind the rear panel. Confirm both legs of 240 V, the fuse and the high-limit first. Remove the canister, move the high-limit thermostat to the new element (it is usually not included), fit the new element and test heat. Some newer platforms put the heater under the drum and need the drum removed.
