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. | ||
|
| 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 | ||
|
|
| 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 |
