- Condition: The dryer’s burner safety device has detected the presence of a pilot flame prematurely out of sequence before the cycle to ignite for pilot flame.
- Alarm Action Taken: MINOR ALARM
- Component: Ultraviolet eye aka “mini-peeper” and Honeywell Burner Control.
- Location: The mini peeper is located up inside the dryer connected to the end cap of the burner that has the spark plug and pilot gas line connected to it. While the control unit is mounted inside the red control cabinet on the lower backing panel. This device is blue in color with a digital display on the face of the unit normally identified by the label “Honeywell Burner Control”
Tech tip: (Control is 115 vac, Mini-peeper 0-5 vdc)
The burner control unit monitors and controls several circuits of the burner. It controls when the pilot solenoid opens and when the ignitor sparks as well as the clean air purge time and the time of ignition allowed before going into alarm. Once the pilot is safely established, it opens the main burner valve to ignite the entire burner.
The mini-peeper is reporting back the presence of flame when there shouldn’t be any.
Tools Required for Service:
- Voltage/continuity meter
- Small standard blade screwdriver (to remove control unit from base)
- #2 Philips screwdriver (wiring terminals on base)
Potential Causes of this Alarm Condition:
- Faulty Mini-peeper
- Pilot solenoid valve stuck open leaking gas up to the pilot section of the burner
- Main burner has gas leaking past both maxon valves up to the burner
- Stray voltage onto the mini-peeper circuit giving a faulty voltage reading
