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. | |

|
|
| 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. | |

|
| 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 | |

|
|
|
| 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. |
