* Refer to LED diagnostic Fault Code Chart.

Is the power across

the 24V wire on the

circuit board and

ground 24V?

Is the

circuit board

sending 120V

to the fan?

Is the fan

obstructed?

Remove

obstruction.

Is the pressure

switch stuck in the

closed position?

Replace

switch.

Yes

Is there 120V on the

primary side of the

internal transformer?

The relay board is faulty

and must be replaced.

The circuit board is

faulty and must be

replaced.

Repair wiring between

power in and transformer.

The fan is faulty and must be replaced

The internal

transformer is

faulty and must

be replaced.

Is the power across

the t-stat wire on the

circuit board and

ground 24V?

Yes

Is the power across

the middle (low)

terminal of 24V plug

and ground (screw on

the Burner Control

Box) 24 Volts?

Repair thermostat or wiring

from thermostat to heater.

Is there 24V

across the TH and

ground terminals

on the circuit

board?

Correct wiring.

Is the circuit

board sending

120V to the

fan?

Is the fan

obstructed?

Remove

obstruction.

Is the pressure switch stuck

in the closed position?

Replace

pressure

switch.

Yes

Check for loose wiring or

restrictions in hose connec-

tions to pressure switch.

Are they OK?

Replace wiring or hose connections.

*After 10-12 minutes of non-

operation has passed, is

there a flash code for APS

failure (2 or 3 flashes)?

Replace the pressure switch after verifying:

• Baffle(s) are in the radiant tube furthest from

the burner.

• Heater, fan blowers ,squirrel cage, intake and

exhaust are clean and free from dirt and

obstructions.

• The 4” air intake pipe does not exceed 20 ft.

and/or 2 elbows.

• There is not a negative pressure experienced

at the area of air intake (e.g.; high winds, attic

space, tightly sealed building).

Replace circuit board.

Yes
