Check for line voltage to the relay coil. If no voltage is present, trace wiring back to the control box hi-limit thermostat(s). If voltage is present, check to insure contacts are closing. Replace relay as needed. Terminals are normally closed. If open, reset and test oven for proper operation. If thermostat will not hold for maximum oven temperature, and oven is not exceeding maximum temperature dial setting, check for proper location of capillary bulb in its spring holder If above checks OK, replace hi-limit.
Check for line voltage to the contactor coil. If no voltage is present, trace wiring back to the oven cavity hi-limit thermostat(s). If voltage is present, check to insure contacts are closing. Replace contactor as needed.
Check, replace if necessary. Check, replace if necessary.
Check for supply voltage to the primary of the control transformer. If no voltage is present, trace wiring back to the oven control relay. If primary voltage is present, check for 24VAC at the transformer secondary. If there is primary voltage, but no secondary voltage, replace control transformer.
Check for 24VAC supply to control. If no voltage is present, trace wiring back to control transformer. If 24VAC is present, check for a read-out on the control display. If there is 24VAC supplied, but there is no read-out on the control display, replace the oven control.
If there is a read-out on the control, set the control to maximum temperature (see installation operations manual for temperature adjustment). With the control set at maximum temperature, check for line voltage at the heat relay (mercury contactor). If there is voltage at the heat relay, proceed to “Heat relay” for next check. If there is no voltage at the heat relay, trace wiring back to the oven control. If there is no voltage output at the oven control, check the read-out on the control. If the control reads “LP FAIL” or “RP FAIL”, this indicates that the thermocouple has failed or has become disconnected from the control. “LP FAIL” indicates a problem with the left thermocouple probe, and “RP FAIL” indicates a problem with the right thermocouple probe.

 

Cooling fan thermostat(s)

Check the cooling fan thermostat. (Thermostat closes

 

 

at 49°C and opens at 38°C). With the cooling fan

 

 

thermostat preheated, check for continuity. If switch is

 

 

open, replace.

 

Fuse, 3 A., cooling fan

Check, replace if necessary.

 

Fuse holder

Check, replace if necessary.

 

Cooling fan(s)

Supply voltage should now be at these motors. If

 

 

voltage is present, check motor for opens, shorts or

 

 

grounds. WITH POWER OFF: Check for locked rotor.

Oven will not heat

Fan switch

Check to see that the fan switch is on.

 

Main oven fan

Check if main oven fan is operating. If not, refer to

 

 

“Oven fan will not run”.

NOTE: These ovens utilize 2 complete /Temperature control systems. Each system will Follow the same troubleshooting sequence.
