## Thermostat Test

Replace the thermostat if it is open at room temperature.
To test a closed thermostat:

1. | Suspend the thermostat (A) in a container of water. Do not let 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.
