11d Troubleshooting — control module lights (cont.)

CHART 6 — PRESS SWITCH light flashing and POWER light on steady

— Usually indicates pressure switch opened during run cycle —

— May also be caused by wind gusts in excess of 31 mph for non-direct vent sidewall-vented boilers —

Electrical shock hazard — Wherever you see �TURN OFF POWER�, follow the instructions. Failure to follow instructions could result in severe personal injury, death or substantial property damage.

•Reset boiler control by turning off power at service switch or turning down thermostat for at least 45 seconds.

•Thermostat should call for heat and appropriate zone valves open.

Does blower motor operate?

No

Yes

•Remove INDUCER plug (Figure 25, Item 6, page 46) from plug receptacle of control module.

•Place voltmeter leads across the 120 VAC N and

120 VAC H pins of the INDUCER receptacle (left column center and right column bottom pins).

Does the voltmeter indicate 120 VAC?

No		Yes

• Replace inducer assembly.

• Retest.

•Remove one of the wires connected to the pressure switch.

•Check continuity across the switch terminals.

Does the ohmmeter indicate the switch is closed?

No			Yes

• Wait 5 minutes.

Is PRES SWITCH light flashing?

No			Yes

•Boiler should be in normal operating sequence.

•Observe operation until thermostat is satisfied and inducer has completed its post- purge cycle.

•Inspect and check wire harness from control module to pressure switch.

•Reseat connector in control module receptacle.

•If harness is intact and properly seated, but problem persists, replace control module.

•Retest.

Are vent or combustion air passages blocked?
