Summary
The service manual for the Whirlpool Dryer Amana PALE120RAW provides critical diagnostic and troubleshooting information essential for technicians. To initiate the diagnostic tests, specific procedures must be followed, including testing key components like the thermal fuse, thermostat, door switch, and heating element. Each component has clear instructions for resistance measurements and operating temperatures, helping technicians isolate faults effectively. For example, the thermal fuse should show continuity if operational, and if open, both the thermal fuse and thermostat limit must be replaced.
Error state can be diagnosed by measuring resistance across terminals. For the heating element, the expected resistance is between 9.43 and 10.01 ohms, and the thermostat should open at 153°F and close at 138°F. Any deviation from these values indicates a need for part replacement. The tech sheet also includes details for checking the timer and motor, ensuring proper functionality during timed cycles and start-up.
Regular maintenance is essential for optimal operation, including inspecting the cylinder seal for air leakage and ensuring the belt is not slipping. Technicians are advised to replace worn parts like the belt or door switch, and clean excess oil from components to prevent slippage. Proper testing and replacement of faulty parts, as outlined in the tech sheet, will ensure the safe and efficient performance of the dryer.
