Question about Heating & Cooling

Riello oil burner RDB with red plastic cover at the front wont ignite. I've tried bleeding the valve. The motor seems to make an electrical humming noise for about 12 secs, then the system attempts to ignite with a click noise which lasts for about 4 secs before switching off again

The motor should spin when the boiler is switched on. One end of the motor spins the fan the other end works the pump. The control box then starts the transformer that starts a spark. The control box then opens up the oil. The boiler should then light if any of the above or the boiler does not light, the boiler will go to lockout.
From what you say the motor is not spinning, thus it could be the motor or more like the pump.

YOU SHOULD NOT PLAY WITHE THE PUMP

If the wrong setting is made it could 1 burn out the back of your boiler 2 go to soot and the boilers in an hour would be filled up and become a fire risk. 3 not start at all if the setting is too low it is a fine line to get it to work and needs the right tools.

oil eng.

My Coleman furnace 4322/729 model lights the pilot but won't cut in . What could be problem ? Cleared lines Complete


Gas valve not opening? Does it have the exhaust blower that pulls vacuum switch allowing burner to light?
(1) Thermostat not working? Has to complete the circuit in or gas valve to open.
(2)Can be a stuck or bad gas valve. Try tapping the side of the gas valve body while thermostat is calling for heat. Tapping,not pounding. Like lightly,yannow? don-ohio (:^)

My oil furnance is running but when it reches temperature it shuts off and will not come back on until we bleed the lines


You have a small leak on the suction side of the pump between the tank and the pump. when this happens the pump looses prime each time the furnace shuts down and when the furnace tries to fire up again the saftey device trips before the oil gets to the burner.

How do I fix my electric heater


  • sounds like the sensor or bulb that tells it to start the blower is defective/ im not familiar with your unit but this seems the most logical answer most furnace will not turn the blower on right away usually 90 seconds after the ignition but will also run longer to exhume any dangerous carbon monoxide. Electricic heaters are different. What type of unit do you have

Electric Furnace stopped running


You have one of two problems. Either the capacitor for the motor has failed or the motor has failed. I would turn off the power to the unit and see if you can locate the capacitor and remove it. An ac supply or electrical supply house can match up the capacitor. This is relatively inexpensive. Otherwise you will need a new motor.

Cannot get gas to flow to pilot flame with main valve parallel to gas pipe. Is there something I must push to make gas flow to the pilot flame pipe?


you said, in effect: Cannot get gas to light the pilot flame even though manual supply valve is open. Is there something I must push to light [ignite] the pilot? Permalink
The gas supply valve is open, and the pilot gas cutoff valve is open but [it seems like] gas will not flow to the pilot flame because it will not light when I supply a match or lighter flame. I remember there is a button or something I need to press...but where it it? I cannot find it.

It could be a thermostat problem. Also it will seem to run constantly as it tries to heat and one of the elements are working which could be a sequencer problem.
