Can a furnace ignitor be cleaned?
If your furnace has a spark ignitor and it’s working haphazardly, it too could be covered with soot, and a blast of compressed air may be enough to clean it. Compressed air can also clean a blocked pilot tube that is causing the pilot flame to burn weakly or not at all.
Why is my propane heater not igniting?
The most common reasons for a non-working propane heater are a dirty thermocouple, a thermocouple that is too far from the flame, a blocked pilot tube, an empty/overfilled gas canister, and drafts. Fortunately, the majority of homeowners will be able to take care of these issues on their own.
Why is my furnace just clicking?
Loud clicking sounds can be heard when inducer blowers and fan shafts are clogged by buildup or when bearings are worn out. Bearings on the main blower motor might click as the furnace runs because the shaft is rusted or dirty. Cleaning and lubricating the fan shaft will help fix the problem and prevent premature wear.
How long do furnace ignitors last?
about seven years
Don’t worry—an ignitor that goes bad is common for most furnaces. Fortunately, you can replace the ignitor without replacing the full furnace. Most ignitors last about seven years. Keep reading to learn how you can tell if your furnace problem is a faulty ignitor.
What is an intermittent pilot on a gas furnace?
Typically found in induced draft furnaces, an intermittent pilot ignites the burner gas with a high-voltage spark only when the thermostat calls for heat. Once the pilot is lit, and the main burner senses the pilot flame (using a flame sensing rod), the main burner ignites.
What happens if the igniter on a gas furnace is broken?
The igniter is the part of the furnace that lights it up, and once it’s broken, there’ll be no heat. Any number of reasons can be behind a broken igniter. Usually, I first check the pilot light. In case it isn’t working, the problem is most likely with the thermocouple, which I check immediately after.
How do I know if my furnace has a pilot light?
Lastly, if your furnace has a pilot light, check to see if it is lit by peering in through the tiny window at the front of the furnace. The flame should touch the tip of the thermocouple. If your furnace has an electronic ignition instead of a pilot light, check if it is on.
Why won’t my RV furnace ignite?
Thermocouples for RVs aren’t expensive, and anyone can replace them. Another common issue is when the blower begins to blow, but the furnace still isn’t igniting. Normally, this is an electrical issue.
