Check, replace if necessary.

 

 

Hi-limit thermostat,

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 hi-limit

 

 

 

 

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.
