Troubleshooting
Timer Control
w If all the connections are verified and the exhaust blower does not function at all, tap lightly on the
exhaust blower’s motor end cap, this may loosen a tight motor.
w Apply 220 V AC directly to the exhaust blower. If the motor does not run, replace the blower.
w If the motor runs, have your dealer check the harness.
4. The convection blower will not function normally.
Timer Control
w Check all the connections between the controller, switch, and the convection blower against the wiring
diagram.
w If the convection motor will not run, apply 220 V AC to the motor directly. If the motor runs, replace
the fan controller. If the motor does not run, the convection blower has failed. Replace the blower.
w If the convection blower runs on high at all times (no control with the fan controller), check the
connections from the 160°F (71°C) sensor (located on the upper left side of the firewall) and
convection fan controller to the blower. Disconnect one of the wires from the sensor; if control of the
convection blower returns to the fan controller, replace the sensor.
w If the motor is still on high, re-connect the sensor and replace the convection fan controller.
