Water Temperature Switches

1. Disconnect electrical connector from switch and check continuity between switch terminal and body. Switches are located on water valve.
2. With temperature below 86 degrees F., both switches should have continuity.
3. With temperature between 86 and 122 degrees F., only outer switch should have continuity.
4. With temperature above 122 degrees F., neither switch should have continuity.
5. If switches fail to perform as outlined, replace water valve.
