SYMPTOM

POSSIBLE CAUSE

EVALUATION

Oven fan will not run

Incoming power supply

Check circuit breakers. Reset if required. Call power

 

 

co. if needed.

 

Fuse, 2 Amp, control (F7)

Check, replace if necessary.

 

Fuse holder

Check, replace if necessary.

 

Switch, oven fan

Check continuity between switch terminals. Replace

 

 

switch as needed.

 

30 minute time delay relay

Check for supply voltage to 30 minute time delay relay

 

 

at terminals #2 and #3. If no voltage is present, trace

 

 

wiring back to main power switch. If there is supply

 

 

voltage at terminals #2 and #3, check for output voltage

 

 

at terminals #1 and #3. If there is incoming voltage but

 

 

no output voltage, and the main power switch is on,

 

 

replace the 30 minute time delay relay.

 

Relay, main fan

Check for supply voltage to relay contacts, if no voltage

 

 

is present, trace wiring back to power supply. Check for

 

 

supply voltage to the coil of the main fan relay. If no

 

 

voltage is present, trace wiring back to the 30 minute

 

 

time delay relay, check to be sure that the Overload

 

 

Protector contacts are closed. If contacts are open, see

 

 

“Overload Protector” below. If voltage is present, check

 

 

to insure relay contacts are closing. Replace relay as

 

 

needed.

 

Overload protector, main fan

Check to be sure overload contacts are closed. If not

 

 

closed, re-set overload. If contacts do not close,

 

 

replace overload protector. If contacts close, test for

 

 

proper operation. If the overload contacts do not stay

 

 

closed, and the amperage is below the overload

 

 

setting, replace the overload protector.

 

 

3240 should be set at 13A

 

 

3260 should be set at 18A

 

 

3270 should be set at 18A

 

Main fan motor

Check for supply voltage at motor. If no voltage is

 

 

present, trace wiring back to the overload protector.

 

 

WITH POWER OFF: Check for opens, shorts or

 

 

grounds. Turn motor shaft to check for locked rotor.

 

Capacitor

Check for shorts or grounds.

 

 

WARNING: Capacitor has a stored charge, discharge

 

 

before testing.

 

Drive belt

Check for loose or broken drive belt. Adjust motor for

 

 

proper belt tension (maximum of 3/8-inch deflection), or

 

 

replace drive belt as needed.

 

 

 

 

Bearings, Fan shaft

Check for any damage or excessive wear on the shaft

 

 

bearings. Replace bearings as needed.
