Burner Ignitor

Check the burner ignitor head for any obstructions,

 

 

also check for frayed or broken wire, any type of

 

 

damage to spark gap (.100 in. 2.5 mm) If there is

 

 

visible damage, replace ignitor assembly.

spark ignitor as the flame sensor. If spark

 

 

continues, check for proper ground connections at

 

 

Ignition Control. Check pilot orifice for any partial

 

 

blockage. If the above checks OK, replace ignition

 

 

control. If spark stops when pilot is lit, check for 24

 

 

VAC across M.V. - M.V/ P.V. terminals, if voltage is

 

 

not present, replace ignition control. If voltage is

 

 

present at terminals M.V. - M.V./P.V., the indicator

across red and black leads, the ohm reading

 

 

should be 0 to1000 ohms as the dial is turned.

 

 

From green to red, the reading should be 1000

NOTE: Ovens S/N Q18037 and above, the potentiometer is internal to temperature control. Proceed to next

Thermocouple Probe

Remove thermocouple leads from the temperature

 

 

control board, and measure the millivolt output of

 

 

these leads. Refer to chart on page 38 in the

 

 

adjustment section for proper readings.

 

Temperature Control

Turn temperature control dial to full "on" position.

 

 

Measure for 120 VAC across terminals "N.O." and

 

 

"L2", if voltage is not present; replace control.

 

Solenoid Valve

If voltage is present at terminals "N.O."and "L2",

 

 

check for voltage at solenoid valve. If voltage is

 

 

present, listen for valve to open and close. Also,

 

 

check for opens and shorts in coil. If solenoid valve

 

 

is defective, replace

Intermittent Heating

 

Both the main fan motor and burner blower motor

 

 

are equipped with thermo-protection and will cease

 

 

to operate when not cooled properly. This can

 

 

cause the units to cycle on and off intermittently.

 

 

Also, most of the problems listed under "oven will

 

 

not heat" can cause intermittent failures.

For continuing intermittent problems, a series of test lights may be made and installed in

the ovens. The lights will allow the customer to advise the service technician a trouble code when the oven fails.

The lights should be connected in the following manner:

Light#l attached in 120VAC line after Air Pressure Switch.

Light#2 attached after 120VAC contacts of Burner Motor Relay (or, refer to Bulletin #028 for Relay Removal).

Light#3 in 24VAC Burner Transformer Secondary.

Light#4 in 24VAC at terminal #6 of Johnson control valve or "24V" on Honeywell Control.
