TROUBLESHOOTING / GAS OVENS 1033, 1034, 1046, 1047

SYMPTOM

POSSIBLE CAUSE

EVALUATION

Oven fan will not run

Incoming Power Supply

Check breaker/reset if required. Call Power

 

 

Company if needed. In these ovens, there is a

 

 

control circuit step-down transformer. This

 

 

transformer steps down supply voltage to 120 VAC.

 

 

If main fan will not run, the secondary of this

 

 

transformer must be checked for 120 VAC output.

 

 

Check specific oven model schematic for circuit

 

 

location.

 

Transformer Fuse

Check and/or replace.

 

Fuseholder

Check and/or replace.

 

Fan Switch

Check continuity between switch terminals.

 

Oven Start Relay

Check for 120 VAC to the relay coil. If voltage is not

 

 

present, trace wiring back to the fan switch. If

 

 

voltage is present, check to insure contacts are

 

 

closing.

 

20 Minute Time Delay

Check for 120 VAC at terminal #1 to neutral on the

 

 

20-minute timer. If no voltage is present, trace

 

 

wiring back to the power supply. If voltage is

 

 

present at terminal #1, check for 120 VAC at

 

 

terminal #2 to neutral. If no voltage is present, and

 

 

the oven start relay is closed, replace the 20-

 

 

minute timer.

 

Oven Fan Relay

Check for 120 VAC to coil of the oven fan relay. If

 

 

no voltage is present, trace wiring back to terminal

 

 

#2 of the 20-minute timer. Check for 120 VAC at

 

 

terminals #2 and 6 of the relay, if no voltage is

 

 

present, trace wiring back to the power supply. If

 

 

voltage is present at the relay coil, check to insure

 

 

the contacts are closing.

 

Fan Fuse

Check, replace if necessary.

 

Fuseholder

Check, replace if necessary.

 

Capacitor

Check for opens, shorts, or grounds.

 

Motor

Check for opens, shorts, or grounds. WITH

 

 

POWER OFF: turn the fan blade to check for

 

 

locked rotor.

No main fan cool down

20 Minute Time Delay

Check for 120 VAC at terminal #2 to neutral while

 

 

oven is "on". Turn off the main fan switch, 120 VAC

 

 

should continue to be present for 20 minutes. If

 

 

voltage is not present for approx. 20 minutes,

 

 

replace the timer.

 

Oven Fan Relay

Check if relay is operating and that the contacts

 

 

remain closed during the 20 minute cool down.

Main fan runs after 20

Oven Start Relay

Contacts should open when main fan switch is

turned off.

 

20 Minute Time Delay

120 VAC at terminal #2 should discontinue

 

 

approximately 20 minutes after main fan is

 

 

switched off. If the oven start relay contacts are

 

 

open, and the voltage continues at terminal #2 of

 

 

the 20 minute timer, replace the timer.

 

Oven Fan Relay

Check to insure that the contacts are opening after

 

 

the coil is de-energized.

No control box cooling
