5.19 Tracing Cooling Fan Faults
Refer to Technical Overview Section 2.7
PROCEDURE:
If cooling fan will not start.
Check cooling fan operation in Technician Mode. (Refer to Diagnostics Section 4.3).
Note: The cooling fan will be operating in low speed when in normal operation. When
the cooling fan is turned on in diagnostics it will run at high speed.
Test for 240volts across contacts or substitute fan with a dummy load. Replace fan if
240 volts is present or if dummy load operates.
(Refer to Servicing Instructions Section 7.16).
Check fan wiring continuity back to power module.
If wiring continuity is good then it is likely that the cooling fan is not faulty. (Refer back to
Symptom Procedure Checklist for further component tests).
If Cooling Fan will not stop.
Check for temperature sensor faults.
(Refer to Section 5.23).
Note: The cooling fan will operate on low speed until the cavity temperature is below
300°F (150°C). If the cavity temperature is above 520°F (270°C) the cooling fan will stay
on high speed.
Replace power module if no other component faults can be found.
