Mid Efficient Propane Furnace Problems
Symptom |
Possible Remedy |
|
No Heat Supply fan will run, combustion fan does not run.
|
Turn the power off to
the furnace for 10 secs, then back on. With the thermostat calling for
heat, does the combustion fan start. If so then your furnace was locked
out on an ignition failure.
With the power off to the furnace, rotate the shaft, it should spin freely. If the bearing are tight replace the combustion fan.
|
| Furnace short cycles, temperature uneven in the house | On
non-electronic thermostats, the cycle rate is controlled by the
anticipator. Remove the front cover, and for access to the anticipator.
This should be set at 0.8 or higher for this type of furnace.
Check the air supply grills, make sure the air from the furnace does not blow directly over the thermostat. If the furnace is over sized, or during mild weather will cause the furnace to short cycle. |
| No heat- Supply fan will run, combustion fan runs but the burner will not start. | Located on or near the vent connection is a back draft safely control that requires you to manually reset the device. There maybe another on in the burner compartment near the burners. This device will trip if hot flue gases spill out from the chimney or the burner area. Reset the control and determined the cause. |
| No Heat-Combustion fan will start, supply fan will run. | When the thermostat calls for heat, the combustion fan should start and run for 30 SEC's, then the ceramic igniter or spark igniter should start. A close visual inspection of the ceramic igniter may reveal a burn mark or a break in the ceramic. These igniter seam to last 5-7 years and then they will burn out or break. Replace the igniter as required. |
