Whirlpool Overheating / Thermostat Stuck Closed

Water too hot, scalding at taps, thermostat set normally

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Stuck thermostat contacts, miswired thermostats, failed gas control thermostat, high-limit not tripping properly

Safety first: Turn OFF power or gas. Warn occupants about scald risk.

Checks:

Verify thermostat settings on electric models; ensure only one thermostat is calling for heat at a time.
Test thermostats for proper opening at set temperature; replace any that remain closed.
On gas models, if water is excessively hot despite normal dial setting, replace the gas control valve/thermostat.

Recommendation: After repair, set temperature to 120°F and consider installing anti-scald mixing valves at fixtures.
