Janitrol aircraft heater will not light

Janitrol heaters can be dangerous things and you should only mess with them if you know what you are doing. Since you have asked the question here, I might assume you don't know what you are doing and as such I would advise you to take it to a qualified technician. There was a case of a Janitrol heater exploding in flight, blowing the nose off a piper Aztec. Luckily for the pilot, the good old Aztec has a tubular metal frame at the front, which supports all the necessary structure including the nose landing gear. He was able to fly the aircraft and land safely, although it was a bit cold and draughty.
The Heater has a built in logic sequence. If any parameter fails it will not start. First it needs combustion pressure which is supplied by the fan. Then it will check the overheat switch and if it is cold enough it will start the ignitor. If all the ducks are in a row it will finally allow the fuel to be injected, but if the fuel pressure is not sufficient the fuel solenoid will not open. If the fuel is injected with no spark, any subsequent spark will blow it up. That is why you don't mess with it. Testing different items out of sequence can cause the item to stop or start at the wrong time. If at any time the start sequence is interrupted, the whole start sequence will start again from the beginning after at least one minute of purging air has been pumped through the unit by the blower fan. If the fan is tired or the airflow has been restricted or too much fuel is injected, the unit will overheat and will automatically switch off the fuel. The fan should continue to run, but generally a manual reset is required to alert the operator that an overheat condition existed and may still exist.

Hope this helps.

I hooked up a coleman electric furnace to a janitrol condenser heat pump . The t-stat wires on electric furnace are red white green and yellow. I added a blue for common off of transformer for digital...

Hi, first of all you need to get a hand full of 5 amp auto type fuses and install one on the hot leg of the 24 volt secondary side of the transformer. Just use 2 female crimp on connectors and put the fuse in the middle of the hot wire. Saves $$$$ on replacing transformers when you have a dead short on the low or high voltage side of any transformer, just a trick of the trade, food for thought. Fuses are much cheaper. On your electric unit, you may not need the common on this to operate the digital stat if it has batteries. This may be your dead short. On the Janitrol condenser, the red is your 24v as you no. They are using blue in place of yellow for cooling. Red is hot, W is heat, G for fan, and blue is cooling on this Janitrol. Keep in mind you are connecting to a heat-pump also, so make sure the wiring is correct. Are you installing this for secondary Heat?? More then likely, the blue common you have added is the dead short as the janitrol uses the blue for a cooling relay in place of yellow. Anyway, use the 5 amp fuse, trick of the trade to save on the transformers. Please keep me posted, as I know know you have this under control.

First, replace the limit. What causes a furnace to cycle frequently would be either a malfunctioning thermostat, a shorted thermostat wire, a bad control or the thermostats heat anticipator is not set right.
