Box-type filters generally have an arrow somewhere along the edge that indicates the direction of air flow through the filter. When box-type filters are dirty, throw them away and install new. If your blower does not shut off and it’s not blowing cold air, then that means the burner is still lit. You do not want the blower to stop if the burners are still lit.

Instructions are usually posted on the side of the furnace. It may be closed, or the switch may have been turned off. The sounds may indicate a mechanical problem, airflow reductions or a clogged burner.
If your furnace is not operating, one of the first things you should do is check the safety switch on the furnace door. A furnace door safety switch prevents the fan and burner from coming on while the access panel is removed. Beyond basic maintenance, it’s not a bad idea to get furnace inspections either bi-annually or annually. Inspections ensure early detection of significant potential problems. The technician will conduct specific testing of the equipment using a standardized procedure. This inspection will help you take steps to alleviate the problem before it worsens and causes a major repair or replacement.

Some blowers are belt-driven meaning there’s a belt between the motor and blower, although this type of set-up is rare in a manufactured home furnace. If you have a belt-drive system, then maintenance should include inspecting the belt for wear and proper tension. A thermocoupler only costs a few dollars and is available anywhere including stores like Walmart. Thermocouplers come in various lengths and length is not important in how it functions as long as it reaches from the gas valve to the pilot light. If you hear a click in 25 seconds or less, replace the thermocoupler and clean the pilot light. If you hear a click in seconds, your thermocoupler is probably fine.
The fan limit switch is a safety device that monitors the temperature inside the furnace and shuts off the components when set temperatures are reached. If the blower runs constantly, it may mean the limit switch is malfunctioning. To address this problem, reset the fan limit control switch. If your furnace has a fan control, it may be adjustable. But for the most part the temperature control switches are non-adjustable and are to be replaced if found faulty.

A combination of condensation and soot can cause burners to function improperly, and may cause other furnace problems as well. The burner assembly should be cleaned annually or replaced if the existing one is in poor condition. This means that the furnace is attempting to light the pilot lights or the burners. Resolving ignition and pilot light problems should automatically fix this. Ou might often need to reset your Furnace unit to resolve issues.
To make sure we provide the most qualified technician, please share more about your needs. Locate your fuse box, and look for the switch marked “furnace.” If no such marker exists, then look for the switch flipped opposite of all the others, and then flip it back. If yoususpect a gas leak, and theodor is strong, you shouldimmediately leave your homeand contact your gas utility company. A curtain or piece of furniture may be obstructing the openings of one or more vents, preventing heat flow. The Spruce; a site dedicated to offering practical, real-life tips to help you create your best home; came up with their list of identifying furnace sounds. Also, there should be a flashing light; green or red.
Calling a competent technician is always the most recommended way to troubleshoot your furnace problem. The centrifugal switch senses whether or not the combustion/induced draft blower is running. If running, the switch closes allowing current through the switch to start ignition. On some newer furnaces, a pressure switch may be used instead of a centrifugal switch.
The code is telling you that either the switch is defective or there’s a problem with the combustion air blower. In many manufactured home furnaces, the centrifugal switch is located inside the combustion air blower. In that case, repairing the switch would also mean replacing the blower.
Always refer to the manual or contact the manufacturer. You may also be able to get the anticipator settings by looking at the gas valve for the amp setting. To make the adjustment, lift off the cover from the thermostat and locate the anticipator. If your furnace is running short cycles, the anticipator is probably set on .2 or lower. Check your furnace manual and move the lever or dial to the setting they recommend which is normally in the .3 to .4 range. Some thermostats have an anticipator for both a/c and heat.
If your furnace has a pilot light that’s lit all the time, then you have a standing pilot furnace. On a side note, leaving your pilot lit all year long is a good idea as it helps keep out condensation preventing rust. Next time your forced-air gas furnace acts up, perhaps one of these basic troubleshooting tips will save you a service call. Plus we’ll show you some maintenance tips that will help keep your furnace in top shape. Compared to a gas furnace, an electric furnace is a bit simpler to understand.
