If the control on your AAON Air Handler isn't powering up, the issue might stem from several causes. First, check the 24VAC or 120VAC wiring for any faults and repair them. Next, inspect the thermostat and transformer. Finally, a bad control module could also be the culprit, in which case you should replace it.
What to do if the burner does not light during trial for ignition in AAON Air Handlers?
If the burner in your AAON Air Handler fails to light during ignition, start by inspecting the valve wiring for any faults and repair them. If the wiring is intact, the valve itself may be bad and need replacement. Another potential cause is the control module not sparking, so check and repair the control module.
Why does the burner light but the valve turns off after the trial for ignition in AAON V3-E?
If the burner in your AAON Air Handler lights but the valve turns off after the trial for ignition, consider these potential issues: * Poor flame – adjust for a better flame. * Flame not in contact with spark electrode or sensor – ensure flame is in contact with spark electrode or sensor. * Dirty contaminated flame sensor – clean the flame sensor. * Faulty flame sensor wiring – inspect and repair flame sensor wiring. * Poor ground at burner – improve grounding at burner.
How to fix spark not occurring during trial for ignition in AAON V3-E Air Handlers?
If a spark isn't occurring during the trial for ignition in your AAON Air Handler, begin by inspecting and repairing the spark electrode wiring. If the wiring is sound, check if the spark gap is too wide and adjust it accordingly. If problems persist, the control module may be faulty and require replacement.
