Ignitor/Sensor Assembly

Check for visible damage to ignitor/ sensor

 

 

assembly. If there is no visible damage to the

 

 

components, and no spark, replace the spark

 

 

generator. If there is visible damage to the Ignitor

 

 

sensor assembly, replace it. Also check for frayed

 

 

or damaged wires in burner tube.

 

Gas Valve

Check for 220 VAC supply to gas valve. If no

 

 

voltage present, check reset button on ignition

 

 

control, check all connections for tightness. If there

 

 

still is no voltage at gas valve, replace

No Pilot

Solenoid Valve

If all above are operating properly, but there is no

 

 

pilot flame, check for any obstructions in bypass

 

 

orifice (drilled port through wall inside solenoid

 

 

valve).

will not stay ignited

 

To check for flame sensor operation, connect a

 

 

digital multimeter (capable of measuring D. C.

 

 

micro amperes) between the flame sensor wire and

 

 

terminal "F" on the ignition control or in flame

 

 

sensor lead for Landis & Gyr. NOTE: this is a

 

 

current measurement and the meter must be

 

 

connected in series. Proper current readings

 

 

should be between 2 and 4 micro Amp. D.C. for

 

 

Honeywell, 3 micro amp for Landis & Gyr minimum.

 

 

If these readings are not achieved, replace

 

 

ignitor/sensor assembly. Also check for any type of

 

 

damage to flame sensor wire and connections.

 

 

Ignition Control If there is sufficient flame sensor

 

 

current, but the burner will not remain ignited,

 

 

check reset button on ignition control, if all above

 

 

are okay, replace ignition control.

Red indicator light is

Temperature Control

Check for 120 VAC across L1 and L2 on

on but no main flame

 

temperature control board. If no voltage 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.

 

Temperature Control

WITH POWER OFF: remove the leads from the

 

Potentiometer

temperature control board and measure ohms from

 

 

black and white leads. The ohm reading should be

 

 

0 to 2.5K ohms as the dial is turned through its full

 

 

rotation. From black to red leads the reading should

 

 

be 2.5K ohms and remain steady throughout the

 

 

full rotation of the dial. If the thermocouple probe

 

 

and the control potentiometer check 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 and shorts in coil.

 

 

Replace as needed.
