My honeywell gas suspended garage heater will not come on when the t'stat calls for heat. It is a heat only unit and neither the fan nor the blower motor will come on. The Heater is getting power to it (110v heater) Also, pilot light is not lit. I followed instructions on heater to re-light pilot, but will not light when calling for heat.

The pilot light has to be lit before gas valve will operate. That's a safety feature so the valve won't open and fill the garage with gas and possibly cause an explosion or fire. If you have a standing pilot and can't get pilot to stay lit, it's usually the thermocouple and it will need to be replaced. Once the pilot is lit, the gas valve comes on and heats the combustion chamber up to approx. 100° to 125° a thermostat controlled fan switch will close and bring the blower on.

Hard wiring on newer t-stats calls for a jumper from R to Rh. If that doesn't work, or isn't the problem then check for 24V at the unit board from W to common. If you have 24V there the stat isn't the problem. I don't know if your heater is gas or electrical, so there's not much else to say.

The heater is not coming on. fan will blow cold air but does not heat up.


Assuming you have the T-stat set to the heat setting and set at least 10 degrees above room temperature and have the t-stat set to AUTo (If applicable) then the problem is with the actual heating unit. The T-stat merely turns the unit on.

The model of T-stat you gave comes up as a discontinued model on Honeywell's web site, but it looks to be a manual stat that type of stat would have to be wired with a summer winter switch with electric heat, allowing it to turn on the fan with a call for heat. If yours is a programmable T-stat you would need to select electric heat or in the installers set up change the default setting for fan from unit controls fan in heat to thermostat controls fan.

Honeywell RTH230B will not call for heat.


On a call for heat an internal switch should connect Rh and W, if it does not the stat is bad. Try it with no wires connected.

no the older rheems had a sequencer for the heat that turned on the blower at the same time that the heat strios are energized. so the first thing that you need to do is figure out the sequencer that is keeping the fan running and get it replaced.

My heating/cooling blower (not the outside unit but the fan in the garage) does not turn off, even when my Honeywell TH8000 is set on automatic. What can I do to have the fan motor shut off?


try hard wiring your 24 volt that goes to the outside unit to the yellow wire coming back from your thermostat make sure the yellow wire is on the yellow terminal on the thermostat (honeywell) i have run into situations when this seemed to be the only thing that worked
