SYMPTOM

POSSIBLE CAUSE

 

EVALUATION

 

Oven fan will not run

Incoming power supply

 

Check circuit breakers, reset if required. Check

 

 

 

power plug to be sure it is firmly in receptacle.

 

 

 

Measure incoming power, call power co. if needed.

 

Fuse, 10 Amp

 

Check, replace if necessary.

 

Fuse holder

 

Check, replace if necessary.

 

Hi-limit thermostat,

 

Check for voltage on both sides of switch. Terminals

 

control box

 

are normally closed. If open, reset and test oven for

 

 

 

proper operation. If thermostat will not hold, and

 

 

 

control box temperature is not exceeding 140°F

 

 

 

(60°C), replace thermostat.

 

Switch, main power

 

Check continuity between switch terminals. Replace

 

 

 

switch as needed.

 

 

Main fan motor

 

Check for 120VAC at motor. If no voltage is present,

 

 

 

trace wiring back to main power switch.

 

 

 

WITH POWER OFF: Check for opens, shorts or

 

 

 

grounds. Turn fan blade to check for locked rotor.

 

Capacitor

 

Check for shorts or grounds.

 

 

 

WARNING: Capacitor has a stored charge,

 

 

 

discharge before testing.

No control box cooling

Incoming power

 

Check circuit breakers, reset if required. Check

 

 

 

power plug to be sure it is firmly in receptacle.

 

 

 

Measure incoming power, call power co. if needed.

 

Switch, main power

 

Check continuity between switch terminals. Replace

 

 

 

switch as needed.

 

 

Cooling fan

 

Check for 120VAC at cooling fan. If no voltage is

 

 

 

present, trace wiring back to power switch. If voltage

 

 

 

is present, and motor does not run, check for opens,

 

 

 

shorts or grounds.

 

 

 

 

WITH POWER OFF: Check for locked rotor.

No automatic control box

Incoming power supply

 

Check circuit breakers, reset if required. Check

cooling

 

 

power plug to be sure it is firmly in receptacle.

 

 

 

Measure incoming power, call power co. if needed.

 

Cooling fan thermostat

 

Check the cooling fan thermostat. (Thermostat

 

 

 

closes at 120°F and opens at 100°F). With the

 

 

 

cooling fan thermostat pre-heated, check for

 

 

 

continuity. If switch is open, replace cooling fan

 

 

 

thermostat.

 

 

Cooling fan

 

Check for 120VAC at cooling fan. If no voltage is

 

 

 

present, trace wiring back to cooling fan thermostat.

 

 

 

If voltage is present, and motor does not run, check

 

 

 

for opens, shorts or grounds.

 

 

 

WITH POWER OFF: Check for locked rotor.

Oven will not heat

Gas supply

 

Check for adequate gas supply to oven.

 

Manual gas shut off valve.

Check to see that the manual gas shut off valve is

 

 

 

open. Also check flexible gas line connection for any

 

 

 

damage.

 

 

Main fan

 

If not operating, refer to “Oven fan will not run”.

 

 

 

 

Centrifugal switch of main fan

Check for 120VAC at wire #5 (input to centrifugal

 

motor

 

switch, located at 6-pin connector in raceway near
