To determine if an “over heating” condition is
caused by a faulty thermostat: Fill the pan with hot
water about 1” (2.5 cm) above the thermostat bulb.
Turn unit on & monitor the water temperature for at
least 30 minutes. Does the water temperature exceed
180 F (82 C)?
If yes, replace thermostat.
To determine if an “under heating” condition is
caused by a faulty thermostat: Fill the pan with hot
water about 1” (2.5 cm) above the thermostat bulb.
Turn unit on & monitor the water temperature for at
least 30 minutes. Does the water temperature reach
at least 150 F (65 C)?
If no, replace thermostat.
Replacement Procedures
Remove side service panel.
Remove thermostat mounting screws & acorn nuts.
Disconnect thermostat wires.
