Power venter improperly wired. 2. Main burner did not light on call for heat. 3. Defective control board. 4. Loss of pressure. Pressure switch not made. 1. Check power venter circuit per wiring diagram. 2. Heater is in lockout mode check flash code table for problem. 3. No flash codes present along with no call for heat, replace control board. 4. Check venting for blockage. Check tubing for blockage or hole. Check spud for blockage. 36 Table 10A - Troubleshooting with LED Indicator Assistance for UT Control Board Line voltage power can cause product damage, severe injury or death. Only a trained experienced service technician should perform this troubleshooting. 1. Check the system thermostat to make sure it is calling for heat. (Do not cycle the thermostat on and off at this time.) 2. Remove the access panel. Do not interrupt power to the control board by opening any electrically interlocked panels. 3. Observe the LED indicator on the control board (a green LED labeled “OK” indicates system faults); check and repair system as noted in the chart to the right. *NOTICE: Air flow proving switch and power venter hose barbs must be free of any dust or debris at all times. Periodically check these openings and/or if any problems occur. LED STATUS INDICATES CHECK/REPAIR Slow Flash Control OK, no call for heat. Not ApplicableFast Flash Control OK, call for heat present. Not ApplicableSteady Off Internal control fault, or no power. 1. Line voltage on terminals 120 and C on transformer. 2. Low voltage (24V) on terminals 24 and C on transformer. 3. 5 Amp fuse on circuit board. Steady On Control internal failure or bad ground. 1. Common side of transformer grounded to chassis. 2. Loose spark ignitor. 2 Flashes In lockout from failed ignitions or flame losses. 1. Gas supply off or gas supply pressure too low. 2. Flame sense rod contaminated or loose wire. 3. Gas valve switch is off or wires are not connected. 4. Broken or cracked porcelain on flame probe or spark ignitor. 3 Flashes Pressure Switch open with inducer on or closed with inducer off. 1. Obstructions or restrictions in appliance air intake or flue outlet are preventing proper combustion airflow. 2. Moisture or debris in tubing that connects pressure switch and draft inducer. 3. Airflow switch jumpered or miswired. 4 Flashes Limit or rollout switch is open. 1. Open manual reset rollout switch. 2. Gas pressure too high, over fire condition. 3. Incorrect airflow due to blockage or motor not operating. 5 Flashes Flame sensed while gas valve is off. 1. Flame probe miswired or shortened. 6 Flashes On-board microprocessors disagree. 1. Thermostat is interfering with control board. 37 Table 10B - Troubleshooting with LED Indicator Assistance for Honeywell Control Board PATTERN STATUS CHECK/REPAIR Short Flash Control powered (without call for Heat) Not ApplicableHeartbeat Call for Heat: normal operations Not Applicable2 Pressure Switch failed closed 1. Check pressure switch to see if open to start, if not replace switch. 2. Air flow switch jumpered. Remove jumper and check operation. 3 Pressure Switch failed open 1. Look for obstruction or restrictions in appliance air intake or flue outlet that are preventing proper combustion airflow. 2. Moisture or debris in tube that connects pressure switch and draft inducer. 3. Check spud on power venter housing. Make sure it is clear. 4 Limit circuit open 1. Open manual reset rollout switch. 2. Gas pressure is too high, over fired condition. 3. Incorrect airflow due to blockage or fan motor not operating. 5 Flame sensed out of sequence - flame still present 1. Flame probe miswired or shorted. 6+1 Softlockout: Failed to light in four ignition trials 1. Gas supply off or gas pressure too low. 2. Flame sense rod contaminated or loose wire. 3. Gas valve switch is off or wires are not connected. 4. Broken or cracked porcelain on spark ignitor allowing spark to jump to ground and not between end of probes. 6+2 Softlockout: Limit circuit opened during run (recycle counter at its maximum) 1. Open manual reset rollout switch. 2. Gas pressure too high, over fired condition causing high limit to open. 3. Incorrect airflow due to blockage or fan motor not operating. 6+3 Softlockout: Pressure Switch opened during run; did not reclose within 2 seconds (flame lost and recycle at its maximum) 1. Check pressure from drafter and see if it reads above set point on pressure switch. Replace bad pressure switch. 6+4 Softlockout: Flame failed during run (recycle at its maximum) 1. Check sensor wire and make sure it is connected properly. 6+5 Flame sensed while out of sequence and is now gone 7+1 Lockout: Bad fuse detected. 1. Check for short. If no short replace fuse and start unit. 2. If no short is found, check gas valve for possible over amp. condition. Replace gas valve. 7+2 Lockout: Low voltage on 24VAC input 1. Check transformer for proper voltage. Replace transformer if not correct. 7+4 Lockout: Flame Rod shorted to ground or there is a big le...
