Caution

Disconnect air and electrical power and make sure

The thermostat and TCO are assembled as a unit and

failed.

The Quick-Slide clips should be removed from the

thermostat. Remove the two screws holding the

thermostat, and pry the thermostat from the block.

thermostat is slipped into the slot in the heat block

before affixing screws.

The thermal cutout assembly is then removed by

thermal cutout to the head block on the stand off strip.

Remove the other end of the thermal cutout from the

terminal strip with a small Phillips screwdriver.
