the heater.

ets to expose the Operating Control Assembly and
the Manifold Switch Cover.

(See Page 4-2).
6. Disconnect the Thermistor wires on the Control
Board (Connector J5).
7. Remove the Manifold Switch Cover.
8. Unscrew the Thermistor from the Manifold.
9. To replace the Thermistor, reverse Steps 1 through
