Temperature Control

Check for 120 VAC across L1 and L2 on

 

 

temperature control board. If no voltage is present,

 

 

retrace wiring back to power supply. Turn the

 

 

temperature adjustment knob to the maximum

 

 

temperature position and check for 120 VAC at the

 

 

load terminal to neutral. If 120 VAC is not present,

 

 

proceed as follows: If 120 VAC is present and unit

 

 

is not heating, see "Solenoid Valve."

 

Thermocouple Probe

Remove thermocouple leads from the temperature

 

 

control board and measure the millivolt output of

 

 

these leads. Refer to chart on page 59 for proper

 

 

readings. If the thermocouple probe checks good,

 

 

then the problem is usually with the temperature

 

 

control board.

 

Solenoid Valve

If output voltage is present at temperature control

 

 

board, check for voltage at solenoid valve. If

 

 

voltage is present, listen for valve to open and

 

 

close. Also check for opens, shorts in coil. Replace

 

 

as needed.

Temperature Control

Check for 120 VAC across L1 and L2 on

but no main flame

 

temperature control board. If no voltage is present,

(1033-1034)

 

retrace wiring back to power supply. Turn the

 

 

temperature adjustment knob to the maximum

 

 

temperature position and check for 220 VAC at the

 

 

load terminal to neutral. If 220 VAC is not present,

 

 

proceed as follows: If 220 VAC is present, and unit

 

 

is not heating, see "Flame Monitor". Check for 220

 

 

VAC at terminal "COM" on temperature control

 

 

board. If no voltage is present, trace wiring back to

 

 

ignition control.

 

Thermocouple Probe

Remove thermocouple leads from the temperature

 

 

control board and measure the millivolt output of

 

 

these leads. Refer to chart on page 59 for proper

 

 

readings. If the thermocouple probe checks good,

 

 

replace temperature control.

 

Flame Monitor

Check for 220 VAC at terminal #1. If no voltage is

 

 

present, trace wiring back to temperature control.

 

 

Check for 220 VAC output at terminal #8. NOTE:

 

 

There is a delay of up to 2 seconds for 220 VAC

 

 

output at terminal #8. If there is no voltage output

 

 

at terminal #8, check the reset button. Replace

 

 

control as needed.

 

Relay, Main Burner

Check for 220 VAC at relay coil, if no voltage is

 

 

present, trace wiring back to flame monitor. Check

 

 

for 120 VAC to relay contacts. If no voltage is

 

 

present, trace wiring back to power supply. Check

 

 

to ensure contacts are closing. Replace relay as

 

 

needed.

 

Valve, Temperature

Check for 120 VAC at valve, if no voltage is

 

Regulation

present, trace wiring back to relay. If voltage is

 

 

present, listen for valve to open and close. Check

 

 

for opens or shorts in coil. Replace as needed.
