My Heater Will Not Work
You have no heat and you have no idea why you just know the furnace is not lighting. In one of my other articles I told you about how prominent the thermocouple is to the standing pilot furnace.
My Heater Will Not Work
In this narrative I would like to talk about other type of heater igniter the direct spark ignition. I will explain the function of it and try to help you understand what you can do to help yourself when it comes to repairing this igniter.
There are steps that each heating system follows called sequence of operation, the doing of a direct spark system as follows.
1. A call for heat is created by the thermostat.
2. The small fan (induced draft motor) will start.
3. A signal is received by the ignition module.
4. Voltage is applied from the ignition module to the sparker (a ticking sound may be heard) causing the burners to light.
5. Within less then a slight the blower or fan should start to turn sending warm air in to the home.
The spark ignition is just that, a small spark is used to light the pilot light or the burner depending on the system. There will be a white box or module mounted in side the unit with any small gauge wires attached to it. There will be a thicker wire among all the rest it will be attached to a steel rod. Like a spark plug in your car a spark is generated between the rod and other metal surface.
The rod can become dirty and may need to be cleaned, but it is rare that it is the reckon for the furnace failing to light and contribute heat to your home. What my happen is the thick wire that connects the igniter rod to the ignition module may become loose or disconnected all together. It is a lot like a spark plug wire so it may become dry and crack so it will not carry the electrical fee to the rod. The wire will need to be supplanted and can be found at your local appliance parts store.
The ignition module can and will fail for any reckon it chooses. If you succeed the steps and find that there is no ticking sound coming from the area of the sparker rod then it is a safe bet that you have a bad module and while you can if you pick fix it your self it may be a good time to call a local mend company. The technician will have palpate with your equipment and be able to prognosis and mend the qoute quickly.
One other item that should be red flag to a bigger problem, that would wish a aid technician, would be, if when you call for heat from the thermostat, this is depending on the type of heater you have, that the inducer motor does not start up. Make sure that you check to see if you have power at the heater. Once you have determined that, then you should call a aid technician.
