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,
control box
Check for voltage on both sides of switch. Terminals
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
cooling
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.
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
motor
Check for 120VAC at wire #5 (input to centrifugal
switch, located at 6-pin connector in raceway near
