WARNING: Inspection, testing and repair of electrical equipment should only be performed by a qualified service techni-

cian. Many of the tests require that the unit have power to it and live electrical components be exposed.  
USE EXTREME CAUTION WHEN TESTING THE MACHINE. 

TROUBLESHOOTING SECTION 

17

Possible Cause

Action

Gas flow interrupted.

Check manual gas valve is open.                

Check regulated gas pressure. (4.0 -6.0 
WCI) for town gas.

If gas line diameter is less than 1/2" 
(1.27cm) or gas line greater than 16 feet 
(4.88m), reduce pressure may result.

Combination gas cutoff valve is closed. 

Ensure 12 VDC to both sides of valve. If 
not, check ECO and DSI. If yes, valve may 
have failed shut. Replace valve.

Modulating valve forced out of normal range 
and may be stuck (common occurrence 
during shipment).

Tap on gas supply line between the 
combination cutoff valve and the 
modulating valve.  This tapping helps to 
free the piston.

Ignition wire loose or broken.

Check wire for continuity.  Check 
connection to both the DSI and spark 
probe. 

Improper gap on spark probe.

Check height of probe above burner (should
be 1/8"(.318 CM)). Check gap between 
probe ends (1/8"(.318 CM)).  Ensure probe 
is not touching burner.

Defective DSI.

Disconnect ignition wire from DSI spade 
connector. During ignition, a spark should 
be seen at this spade.  If none, replace DSI.
If spark exists, replace ignition wire.

Improper operation of modulating valve. 

Check voltage to modulating valve.  If 
greater than 2.0 VDC, modulating valve 
may have been forced out of its operating 
range. Tap on gas supply line between the 
combination cutoff valve and the 
modulating valve. This tapping helps to free 
the piston.  If less than 2.0 VDC, replace 
control board.

Symptom

Green LED flashes, but no ignition (igniter 
sparks, no gas).

The unit ignites, but will not rise above 
ignition burn.

Green LED flashes, but no ignition (no 
igniter sparks, gas flow and smell present).
