SYMPTION

POSSIBLE CAUSE

EVUALATION

 

Oven will not heat

 

Gas Supply Manual Gas

Check for adequate gas supply to oven. Check to

 

 

 

Shut-Off Valve

see that manual shut-off valve is open.

 

 

 

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."

 

 

 

Burner Switch

Check for 220 VAC to neutral on both sides of

 

 

 

 

switch. If switch is closed, and 220 VAC is present

 

 

 

 

on one side only, replace switch .

 

 

 

Gas Pressure Switch (internal

Check for 220 VAC to neutral on both sides of

 

 

 

to gas valve)

switch. If voltage is present on one side of switch

 

 

 

 

only, check the following. Check for proper gas

 

 

 

 

pressure supply to gas valve. (Marked on oven

 

 

 

 

spec plate) Check for proper adjustment of gas

 

 

 

 

pressure switch. Should be set at 8.8 Nat., 23 L.P.

 

 

 

 

2.0 Town Gas. Check gas filter in gas valve for

 

 

 

 

blockage or damage. (See Adjustment Section for

 

 

 

 

location) If the above checks okay, but switch still

 

 

 

 

not closed, replace gas valve.

 

 

 

Air Pressure Switch

Check for 220 VAC on both side of switch. If

 

 

 

 

voltage present on one side only, check for air tube

 

 

 

 

blockage or misalignment adjust air switch. If above

 

 

 

 

fails, replace air pressure switch.

 

 

 

Hi-Limit Thermostat

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 temperature dial setting, check for

 

 

 

 

proper location of capillary bulb in its spring holder.

 

 

 

 

If above checks okay, replace hi-limit thermostat.

 

 

 

Ignition Control

Check for 220 VAC supply to ignition control at pin

 

 

 

 

#1 and neutral. If voltage is not present, retrace

 

 

 

 

wiring back to hi-limit thermostat. Check for 220

 

 

 

 

VAC at pin #6 to neutral. (Power to burner motor

 

 

 

 

relay). If voltage present, proceed. If no voltage is

 

 

 

 

present, wait 30 seconds and check reset button. If

 

 

 

 

above fails, replace ignition control.

 

 

 

Burner Motor Relay

Check for continuity to 220 VAC coil. Check for

 

 

 

 

power to relay coil (220 VAC). Check for 120 VAC

 

 

 

 

to relay contact terminals. Visually check for

 

 

 

 

contact pull-in.

 

 

 

Burner Blower Motor

Check for 120 VAC supply to burner blower motor.

 

 

 

 

WITH POWER OFF: turn blower wheel to check for

 

 

 

 

locked rotor. If 120 VAC is present and motor does

 

 

 

 

not run, replace motor.

 

 

 

Burner Blower Motor Air

Check for 220 VAC switching to pin "N.O." as the

 

 

 

Pressure Switch

air pressure switch closes. Connect a temporary

 

 

 

 

jumper wire (for testing purposes only) from pin "C"

 

 

 

 

to pin "N.O." on ignition control (to bypass air

 

 

 

 

switch). NOTE: For Honeywell control only. Check

 

 

 

 

for air tube blockage or misalignment, adjust air

 

 

 

 

pressure switch. If the above fails, replace air

 

 

 

 

pressure switch.

 

 

 

Spark Generator

After a pre-purge time of 30 to 60 seconds after

 

 

 

 

blower motor starts, check for 220 VAC to spark

 

 

 

 

generator. If voltage is not present, check reset

 

 

 

 

button on ignition control. If voltage is still not

 

 

 

 

present, replace ignition control. f voltage is

 

 

 

 

present, visually check for spark at ignitor head.
