SYMPTOM

POSSIBLE CAUSE

EVALUATION

Oven fan will not run

Incoming Power Supply

Check breakers, reset if required Check power plug

 

 

to be sure it is firmly in the receptacle (if applicable).

 

 

Measure the incoming power, call Power Co., if

 

 

needed

 

Oven Fan Fuses, 5 Amp

Check and/or replace

 

Fuse Holder

Check and/or replace

 

High Limit Thermostat

Check for voltage on both sides of the switch.

 

Control Box (Note: High

Terminals are normally closed. If open, reset and

 

Limit not used in ovens

test oven for proper operation. If thermostat and

 

S/N 3000352)

below.) will not hold and control box temperature is

 

 

not exceeding 140°F (60°C), replace thermostat.

 

Fan Switch

Check continuity between switch terminals. Check

 

 

and insure good wire connections

 

20 Minute Time Delay

Check for supply voltage at terminal #1 to ground on

 

 

the 20-minute timer. If no voltage is present, trace

 

 

wiring back to power supply. If voltage is present at

 

 

terminal #1, check for supply voltage at terminal #2 to

 

 

ground. If no voltage is present, and the oven fan

 

 

switch is closed, replace the 20-minute timer.

 

Main Fan Relay

Check continuity of coil. Check for power to relay

 

 

coil. Visually check for contact pull in and contact

 

 

condition. Check for voltage across relay terminals.

 

Fan Motor

Check for opens, shorts, or grounds. WITH POWER

 

 

OFF: Turn fan blade to check for locked rotor.

 

Capacitor

Check for opens, shorts, or grounds. WARNING

 

 

Capacitor has a stored charge, discharge before

 

 

testing.

No main fan cool

20-Minute Timer

Check for supply voltage at terminal #2 and #3 while

down

 

main fan is running. Turn off fan switch and supply

 

 

voltage should continue to be present for 20 min. at

 

 

terminal #2. Replace as needed.

Main fan continues to

20 Minute Timer

NOTE: On/Off operation of fan switch will reset timer

run after cool down

 

to 20 minutes. If timer is accidentally reset, turn off

 

 

main breaker to cancel. If voltage continues to be

 

 

present at terminals 2 and 3 after 20 minutes, verify

 

 

fan switch contacts have opened, replace timer as

 

 

needed.

No control box

Fan Switch

WITH POWER OFF: Close switch and check for

cooling

 

continuity across switch terminals.

 

20 Minute Timer

See "Main Fan Motor will not run."

 

Cooling Fan

Check for voltages at the fan motor, if present,

 

 

replace defective fan motor.
