Testing Thermostats
1. Remove thermostats. (See REMOVE THERMOSTATS
earlier in this group.)
CAUTION: DO NOT allow thermostat or
thermometer to rest against the side or bottom
of container when heating water. Either may
rupture if overheated.
2. Visually inspect thermostats for corrosion or damage.
Replace thermostats as a matched set as necessary.
3. Suspend thermostats and a thermometer in a container
of water.
4. Stir the water as it heats. Observe opening action of
thermostat and compare temperatures with
specification given in chart below.

vary slightly from specified temperatures.
5. Remove thermostat and observe its closing action as it
cools. In ambient air the thermostat should close
completely. Closing action should be smooth and slow.
