Thermostat Test
Replace the thermostat See: Service and Repair if it is stuck in the open position at room temperature.
To test a closed thermostat:
1. Suspend the thermostat (A) in a container of water. Do not let the thermostat and the thermometer (B) touch the bottom of the hot container.
2. Heat the water and check the temperature with a thermometer. Check the temperature at which the thermostat first opens, and at which it is fully
open.
3. Measure the lift height of the thermostat when it is fully open.
