Possible Causes

Multiple sensor errors, Main control board failure, Wiring harness issues, Power surge damage

Safety First: Disconnect power before inspecting internal components.

Steps:

Enter diagnostics: Many Whirlpool models allow entering service mode via a button sequence (see tech sheet). Note any stored sensor or fan errors.
Check harnesses: Inspect main harness connections at the control board, fans, and thermistors.
Power reset: After reseating connectors, restore power and see if the C code clears.
If the code persists and individual components test good, replace the main control board.
