Check your breakers, look for blown fuses for the transformer, could be a blown transformer and could also be a bad thermostat. Thermostats are easy to rule out; just take a wire and and jumper between R and G. If your fan comes on then is at least a T-Stat Problem. This can also indicate ablown transformer circuit, if a gas furnace that the blower compartment is not closed or a bad door switch. Also if you have water safties(float switch or wet switch) make sure your condensate is not stopped up. If you have a wet switch make sure it shows green and not red.

Honeywell thermostat blows cold air on heat


Thermostats don't actually blow anything, the heating system might though. Check the breakers for your heat system, then call a heating specialist. They're really not that expensive.

Honeywell thermostat will not work when put on automatic


Depends on what type of heat you have...if it is electric, it could be your thermostat (some electric heaters use contactors & rely on the thermostat to switch the fan on). Heat pumps also use the thermostat to switch the fan on in heat & cool mode. Most electric furnaces use a sequencer to switch the low speed of the fan whenever there is a call for heat. Gas furnaces use either a fan/limit controller (if the unit is older) OR a circuit board based on time (after the thermostat calls for heat). SO depending on the type of system you have, it could be a bad sequencer, controller, relay, thermostat, or control board. Hope that helps.

Will a th5000 work with a ruud dual fuel


Are you talking about a pro 5000 Thermostat??? if so then NO it will not work.With this stat you do not have a temperature lock on the heat pump. Say you don't want the heat pump to run below 25 degrees. it won't shut the heat pump. And you don't want the heat pump to run at the same time as the furnace. With the Pro 8000 3 heat and 2 cool thermostat you can lock out the heat pump at 25 degrees outside an turn the furnace on. You will have to install an outdoor thermostat hooked up to the pro 8000 it usually comes with the stat. Honeywell products.

Amana PGD60C1152E no heat


Your thermostat Function 0170 must be set to "1" for Single Stage Heat/Cool. Function 0180 must be set for "0" for Heating Fan Control. Function 0240 must be set for "5" for the Heating Cycle Rate for your <90% Gas Furnace. If you have already done these steps or if, after doing these steps, you continue to experience a problem, you problem could be with your Gas Furnace. I'm including some links for information on your system and thermostat that include wiring diagrams.

RHEEM OIL FURNACE MODEL ROBD 067 LBEA BLOWER


You will likely need to install an isolation relay in the W circuit from the thermostat. Some thermostats rob a small current through the W circuit to power the thermostat. This small current can be enough to start the fan circuit timer. You can test this by disconnecting W at the furnace and allowing the timer to shut down. If the fan shuts off with the W disconnected you can install a simple relay.

The relay coil will be connected to Common on one side and the W from the thermostat to the other. Then you will run a wire from R on the furnace to the relay and from the N.O. Contacts to the W terminal on the furnace. This will kill that signal that is starting the timer and the W can steal it's power through the coil back to common.
