2.3 Fault Code

DEFINITION

Stage Gas Valve not energized when it should

be 10 !mes within the same call for heat .

4VAC not sensed on MVL 10 !mes

Replace IFC

There are two flame sense pads located on the IFC,

marked “FP”. To measure flame current, use a VOM set

to DC volts. Flame current will vary depending on the

type of meter used. Typical flame current ranges from

0.75 – 3.0 micro-amps (0.75 – 3.0 VDC)

2.2 Fault Code

Cycle power to

furnace and call for

stage heat

Is manifold pressure

~3.5"WC (NG)

~10.0" WC (LP)

Adjust manifold gas pressure to

~3.5"WC (NG)

~10.0" WC (LP)

Check opera!on

YES

Is minimum outlet

gas manifold

pressure

maintained?

Disconnect electrical

power to furnace.

Connect manometer

to manifold pressure

connector

YES

Disconnect electrical

power to furnace.

Connect manometer to

inlet gas pressure

connector

Cycle power to

furnace and call for

stage heat

Is minimum outlet

gas manifold

pressure

maintained?

Correct incoming

gas supply pressure

YES

Possible Causes

Dirty Sensor

Dirty burners

Poor grounding

Sensor loca!on

Wire connec!ons

Measure flame current. Is

flame current greater

than 0.75 micro-amp?

(0.75-3 µA = Normal)

Possible Causes

Plugs

Blower door

Wind gust

Power interrupt

YES

Possible Causes

Plugs

Blower door

Wind gust

Power interrupt

DEFINITION

RECYCLE Lock Out = 10 recycles within a single

call for heat. Lockout period is for one hour.

Flame is sensed & then lost

All gas appliances in the home should be turned
on to verify gas pressure
