are no obstructions, replace gas control valves.

Flame will not stay lit

Hot Surface Igniter

The ignition control will keep the gas control valves energized

 

 

for 6 seconds. At the end of 6 seconds, the hot surface igniter

 

 

must sense a flame, or, the ignition control will go into lockout.

 

 

(The ignition control requires a minimum of 0.8 microamps

 

 

D.C.) To check the flame sensing operation, connect a digital

 

 

multimeter (capable of measuring D.C. micro-amps) between

 

 

the "ground" terminal on ignition control and the ground lead.

 

 

NOTE: This is a current measurement and the meter must be

 

 

connected in series. If these readings are not achieved, check

 

 

bypass orifice for obstructions, if bypass orifice is clear,

 

 

replace the hot surface igniter.

 

 

NOTE: The D.C. micro amp test must be conducted with the

 

 

oven in low flame (bypass) operation. Turn the temperature

 

 

control to its lowest setting.

 

Power Supply

If there is sufficient micro-amp current, but the flame will not

 

 

stay lit, check for proper polarity of the 120 VAC power supply

 

Ignition Control

If there is sufficient micro-amp current, and the 120 VAC

 

 

polarity is correct, but the flame will not stay lit, replace the

 

 

ignition control.

 

 

NOTE: Check for proper ground connection of the ignition

 

 

control.

 

NOTE: Flame should

 

 

be lit at this time.

 

Low flame is on, but

Temperature Control

Check for 120 VAC at terminal #7 to neutral on temperature

no main flame

 

control. If no voltage, trace voltage back to fuse holder. Turn

 

 

the temperature adjustment knob to maximum temperature

 

 

position and check for 120 VAC at the load terminal #8 and

 

 

neutral. If 120 VAC is present and unit is not heating, refer to

 

 

"Temperature Solenoid Valve" for next check. If 120 VAC is

 

 

not present, proceed.

 

Thermocouple Probe

ATTACHED TO THE TEMPERATURE CONTROL BOARD:

 

 

Measure the D.C. millivolt output of these leads. Refer to

 

 

thermocouple chart on page 17 for proper readings. If these

 

 

readings are not achieved, replace the thermocouple.

 

Temperature Set

Disconnect the potentiometer leads Disconnect the pot from

 

Potentiometer

the board. Place ohm meter test leads on the blue and green

 

 

pot leads. Reading should be 1 K ohms. Place meter leads

 

 

across the blue and purple pot leads and rotate knob from high

 

 

to low. Repeat on green and purple leads. Check for even

 

 

rise and fall of ohms reading to insure that there are no open

 

 

or dead spots in the potentiometer. Check each lead to

 

 

ground for shorts. Replace pot if it does not meet the above

 

 

test
