The winter months are not that far off. Before we know it snow will be falling and chilly temperatures will be settling in. Whether you live in an area where winter lasts for six months out of the year or not, if your Payne furnace has no heat you’re in trouble.
It is not uncommon for a furnace to blow cool air, make bumping or other loud noises, or fail to start. There are some moderately simple steps you can take to remedy a not heat situation.
First, take a look at your air filters. If the blower is constantly running but only blowing cool air the air filters are probably clogged. Debris can create a barrier between the fan and heat, causing you to feel nothing but lukewarm to chilly air. Burr!
You can usually clean a filter using a small vacuum and rinsing the filter with water. Be sure it is completely dry before reinsertion. It is a good idea to check your filters once a month and clean them as needed.
If your Payne furnace has no heat the thermostat may be to blame. Thermostats can wear our over time and need replacing or adjusting. If your unit cycles properly but blows cold air, the thermostat might be faulty and need replacing.
Another possibility is that an overload in the unit’s electrical system caused the power switch to flip to the “off” position. Check to see if this is the case and reset the switch to the “on” position. Circuit breakers can also flip—check them as well. A blown fuse can also cause a lack of heat. If all of these checks out, then the problem might lie with the unit’s thermocouple.
The thermocouple is a safety control. It should be next to the pilot light flame. It has to detect the flame and send an electrical signal to the unit to turn the head on. If your Payne furnace has no heat, the thermocouple might have worn out.
You can order a replacement part from a local dealer or direct from the manufacturer. If your unit is still covered under warranty, a replacement thermocouple should not cost you anything.
