SYMPTOM |
| POSSIBLE CAUSE | EVALUATION |
| |
Oven fan will not run |
| Incoming power supply | Check circuit breakers. Reset if required. Call | ||
|
|
|
| power co. if needed. | |
|
| Fuses, 10 Amp, motor and | Check, replace if necessary. | ||
|
| controls |
|
|
|
|
| Fuse holder |
| Check, replace if necessary. | |
|
| Terminals are normally closed. If open, reset | |||
|
| Oven cavity |
| thermostat and retest. If thermostat will not hold | |
|
|
|
| for maximum oven temperature, and oven is not | |
|
|
|
| exceeding temperature setting, check for proper | |
|
|
|
| location of capillary bulb in its spring holder. If the | |
|
|
|
| capillary checks okay, replace the | |
|
|
|
| thermostat. |
|
|
| Switch, main power | Check continuity between switch terminals. | ||
|
|
|
| Replace switch as needed. | |
|
| Relay, oven start | Check for 120VAC supplied to coil of relay. If no | ||
|
|
|
| voltage is present, trace wiring back to main | |
|
|
|
| power switch. If voltage is present, check for pull | |
|
|
|
| in of relay contacts. Replace relay as needed. | |
|
| 20 minute time delay | Check for 120VAC at terminal #1 to neutral on | ||
|
|
|
| time delay relay. If voltage is not present, trace | |
|
|
|
| wiring back to 10A. fuse. If voltage is present at | |
|
|
|
| terminal #1, check for 120VAC at terminal #2 to | |
|
|
|
| neutral. If no voltage is present, and oven start | |
|
|
|
| relay is closed, replace 20 minute time delay relay. | |
|
| Relay, main fan |
| Check for 120VAC to coil of main fan relay. If no | |
|
|
|
| voltage is present, trace wiring back to 20 minute | |
|
|
|
| time delay relay. If voltage is present, check to | |
|
|
|
| insure that relay contacts are closing. Replace | |
|
|
|
| relay as needed. | |
|
| Main fan motor |
| Check for supply voltage at motor. If no voltage is | |
|
|
|
| present, trace wiring back to main fan relay. | |
|
|
|
| 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 main fan cool down |
| 20 Minute time delay | Check for 120VAC at terminal #2 to neutral while | ||
|
|
|
| the oven is ‘on’. Turn off the main fan switch, | |
|
|
|
| 120VAC should continue to be present for 20 | |
|
|
|
| minutes. If voltage is not present for approx. 20 | |
|
|
|
| minutes, replace the 20 minute time delay. | |
|
| Oven fan relay |
| Check for 120VAC to relay coil, if no voltage is | |
|
|
|
| present, trace wiring back to 20 minute time delay. | |
|
|
|
| If voltage is present, be sure that relay contacts | |
|
|
|
| stay closes during the 20 minute cool down. |
