The heating coil is probably getting plugged up. You may have heat at idle or slow speeds, but once you get going, there is not enough coolant going through it to stay warm. Get the system flushed or replace the heating coil.

You would have air pockets with a new thermostat and none if you leave it out.
Are you sure you are burping the cooling system with the new thermostat installed ?
Its also possible you have a leaking head gasket or other problem that is being amplified by having the thermostat installed. Something may be heating up with and not without.

I have a GMP100 furnace and I replaced the control board because the blower fan wouldn't kick off now and then. It all works great but the main blower only stays on about 45 seconds after the burner turns...


Check the board for a set of dip switches. Check against the old board for switch positioning. These control fan on/off times. Ensure you turn power off before changing switch positions. If no dip switches,??

Ruud air to air heatpump intertherm propane furnace honeywell th5220d non programable thermostate.fan on furnace will not turn off in aux.mode even though the furnace heat kicks on and off. thank you for...


Make sure fan relay is wired correctly (G) wire. Ensure the fan on therm is not on, it should be on Auto or off.

If your furnace is short cycling because it has to keep heating your home, the delay in the control board may be staying on to compensate for the exchangers getting hot. If it heats normally, then put your attention to your thermostat.

Set the heating system on aux heat only. Fan should not be on, if it does stay on after a heating cycle, see if the furnace is heating normally, and reaching temp as desired before the heat comes off. Then check the therm wiring, pull the face of the therm, disconnect green wire (fan) and try the heating again.
