Electronic Control Board for an Electronic Ignition Furnace
Gas Furnace Troubleshooting Techniques - Electronic ignition for gas furnaces is the modern way for furnaces to light the main burners. Furnace technology has evolved from the standing pilot gas ignition systems. These furnaces continue to be used today, however, there are fewer standing pilot furnaces used today than yesterday. When troubleshooting a system it is important to know which type of ignition system the furnace uses. (more…)

Furnace and Boiler Oil Filters - Oil burner oil filters are important to keep trash out of the burner gun and plugging the nozzle. A dirty filter can also choke the system from firing properly by preventing the correct amount of oil flow from reaching the nozzle. Oil furnace oil filters or oil boiler oil filters should be changed on at least an annual basis. More if the oil or oil tank is of poor quality. It is also recommended that the oil furnace or oil boiler be shut down when oil delivery is made.

Gas Furnace with Drain Pipes to Drain the Condensation.
Furnace Water Leak Condensate Problem - Richard, My furnace is leaking water. It is summertime, so I am not using it for heat except for the blower fan which is hooked up to the air conditioner and the heat. I know the pipes from the outside units run into a box on top of the furnace. I think that is a part of the air conditioner. What can I do to fix the problem if you know what the problem is by my explanation here? Dan

Furnace with Hot Surface Ignition
Hot Surface Ignitor - Whenever we talk about electronic ignition systems in gas furnace ignition systems we must first look at the key components which make these systems work and understand how they work. Hot surface ignitor systems work in various ways.
This all depends on what the electronic ignition manufacturer and design engineer determined in the design. Furthermore, some are direct main burner ignition while others light a pilot, and the pilot lights the main burners.

Oil Controls Burner - The oil burner and oil controls provide the main source of heat for this oil furnace. The oil burner comprises an oil pump, an oil pump, a burner electric motor, a burner blower, a step-up transformer, an oil ignition control, an oil burner gun, and an oil nozzle (inside not viewable here).
The burner electric motor is directly linked to the blower and the oil pump and when the electric motor starts (controlled by the ignition control) the pump begins pumping oil while the blower provides primary air to the combustion chamber. (more…)

Gas Furnace Electronic Ignition Control Board
Electronic Ignition Gas Furnaces Types | Gas Heating Systems. Gas furnaces, boilers, and water heaters have evolved from the basic standing pilot ignition system to the state-of-the-art electronic ignition models. Standing pilot gas furnaces relied on keeping a pilot flame lit for the furnace, boiler, or water heater to function. The advent of electronic ignition has made it possible to prove a flame without keeping a pilot light lit 24/7.
That saves money because electronic ignition only needs to have a flame when there is a call for heat. Lastly, no more worries about lighting a pilot light. There are different types of electronic ignition gas furnaces. Remember, this is a classification of gas furnaces. There are other classifications or types of gas furnaces.

White Rodgers Gas Furnace Ignition Control Board
Electronic Ignition Gas Furnace Problems Troubleshooting - Gas furnaces are a prevalent form of heat for homes and businesses, and occasionally a gas furnace needs to be repaired because of a problem with the gas furnace.
Since there are many different types of gas furnaces, it is difficult to cover every single possible gas furnace problem that can occur with a gas furnace in one article. We are going to break this theme “gas furnace problems” down into a series of articles with the first one being gas furnace problems with electronic ignition gas furnaces.

Steps to Light a Pilot Light
- Determine That You Actually Have a Standing Pilot Gas System
- Check to Make Sure You Have Fuel
- Understand the Valve Function
- Light the Pilot Light
- Enjoy the Warmth

How To Light a Pilot Light – Standing pilot gas furnaces and water heaters are still around today even in newer homes. All the major hardware stores and HVAC dealers carry standing pilot appliances. Although a new standing pilot gas furnace or boiler is rare finds these days. Because of the move to higher efficiency models and the wide use of electronic ignition technology which improves efficiency.
Before you proceed you’ll want to determine if you actually have a standing pilot system in your HVAC furnace, boiler, or water heater.
In many cases, on many appliances, there are basic instructions on lighting it, in fact, you do have a standing pilot system. Check around the main panel or look at the gas valve itself. Sometimes, especially on older appliances, there are no instructions on it if the pilot light goes out on a standing pilot gas furnace, boiler, or water heater.
The label or sticker on the furnace, boiler, or water heater faded a long time ago and you will need to follow the instructions in this article. (more…)

Oil Furnace Condensation Problems - This Oil Furnace has flue gas condensation problems as one can see from the white residue forming on the front of this oil furnace. This problem occurs when the flue gases are not hot enough to rise above and out of the flue. (more…)

Honeywell Oil Burner Ignition Control | HVAC Heating - This Honeywell oil burner ignition control controls the oil burner sequence of operation. On a call for heat from the thermostat, the oil burner ignition control starts the burner blower. this mechanically interlinked with the oil pump.
The blower blows air into the combustion chamber and the oil pump pumps oil to the burner’s nozzle. The step-up transformer is energized and applies a very high voltage spark to the burner’s ignitor. When the flame is detected it is immediately detected by a cad cell eye which recognizes the light produced by the flame inside the combustion chamber. (more…)
