Not Applicable
Not Applicable (normal operation)
Check: If inducer is running, inducer could be broken or disconnected, or inducer relay
K4 may have failed.
Check/Repair: Low line voltage; Pressure switch wiring loose; hose disconnected or
leaking; water in hose; venting blocked or obstructed.
Check: If inducer is off; inducer relay (K4) could be welded.
Check/Repair: Terminal wiring (shorted); pressure switch contacts (closed when should
be open); pressure switch hoses have water build-up or obstruction.
Check: See if inducer is running.
Check/Repair: Restricted venting; low input voltage; water in horizontal vent length.
Check: Wiring; restricted airflow through heat exchanger; clogged filters; slow circulator
fan speed.
Repair: Remove restrictions. Increase airflow through furnace (increase motor speed,
open more ducts, add more returns).
Check/Repair: Gas valve leakage.
Check/Repair: Gas supply (pressure, supply, shut-off valves, gas valve); ignition (HSI
element not properly positioned and glowing); flame sensing (lead-wire broken or
grounded, flame rod not properly positioned, or flame rod contamination); low line
voltage.
Check/Repair: Pressure switch wiring; slow inducer; restricted, excessive, or obstructed
venting; unstable line voltage.
Check/Repair: Gas supply; flame sensor wiring.
Check: Wiring; restricted airflow through heat exchanger; clogged filters; slow circulator
fan speed.
Repair: Remove restrictions. Increase airflow through furnace (increase motor speed,
open more ducts, add more returns).
Check/Repair: Gas valve, Gas valve wiring.
Replace S9200U1000 if problem persists.
