Can installing a new digital thermostat cause a board to fail in the furnace blower?

sounds like problem with tstat programming.

what is the sequence to a gas furnace ? The sequence how a gas furnace works normally is : thermostat calls for heat, blower comes on for a few seconds and is shut off, gas valve opens and an igniter lites up and burners come on giving heat to the heat exchanger. When a certain temperature is reached depending on the make of the furnace normally around 120f blower comes on. When temp. is satisfied…

Yes it is. It contains the blower.

This is a terrible question. Installing it on what? Learn how to ask better questions!

To add the sae 10 non detergent oil to your furnace blower motor you will have to open the motor section.

Yes, It`s on the inside of the blower compartment cover panel.

The operation of the furnace depends upon the thermostat, which is a simple unit that like a thermometer. which has set at a particular temperature. If this value falls below the set level on the thermostat, then the house starts to become colder, which alerts the electric furnace that is usually situated in the basement of a building. The heated coil in turn heats the temperature of the air around it. This air is then…

Furnace blower motors are easily found at HVAC installers and repair centers. However, without proper knowledge, a customer should not try to fix this, it can be dangerous.

It could have any size heating furnace, the two are unrelated except for the size blower used in the furnace to support the 3 ton cooling system. But the fact remains you can get a 3 ton blower in 50,000 btu furnace, a 100,00 btu furnace and anything in between.

I have a Frontier Campervan conversion on this vehicle type and can answer for that. 1) Turn on the propane at the tank. 2) Take the front panel off the furnace by pulling the top straight out then lifting. 3) Turn the propane on at the furnace by rotating the red knob 1/2 turn to the ON position. 4) Replace the furnace cover. 5) The wall thermostat has an ON/OFF switch on the bottom. Click…

the blower motor is pulling too much amperage

I was quoted $185. Charlotte, NC.

I have this same type of sill furnace and the filters goes on the inside closest to the blower.

Here is a short list of the most common causes: air filter is plugged low on refrigerant breaker is tripped batteries in thermostat need to be replaced furnace or air handler blower door is off or improperly installed thermostat not set correctly

Furnace blower plugged in, to a live outlet? Fuel (natural gas or oil) is sufficient? If your thermostat has a battery, you may need to replace the battery; that happened to me last year.

turn off power to furnace and remove the bottom door to the blower compartment,the filter should be on the right side of the blower housing or it may be directly below the blower housing on the bottom of the furnace depending on how your return duct is run. hope this helps,FYI filters s/b replaced or cleaned every 30 days.

Check the circuit breakers for both, doubtful both have simultaneously failed.

This means there is a blower attached to the system that forces the heat into the home.

On the inside of the blower panel door.

If you have a 2 stage furnace (hi fire & lo fire) then the blower will run on lo speed in lo fire & hi speed in hi fire and in AC mode. If it`s a single stage furnace lo speed for heat and hi speed for cooling.

This is how a furnace heats your home. When the thermostat calls for heat, a signal is sent to the gas valve. If you have an older unit, the gas valve checks to see that the thermocouple sees the pilot and if it does, the gas valve opens to send gas to the burners. If you have a newer furnace, the thermostat sends a signal to start the pilit ignition sequence (either spark or hot…

It depends on the rating of the furnace. There should be a plate or sticker somewhere on the furnace that shows the rating. If you are just powering a blower motor the rating will be lower than if you have an electric heating element.

This operation requires a licensed electrician. Not recommended to a DIYer.

There is usually a wiring diagram/schematic on the inside of the blower/fan door.

There should be only one blower to move the air. The unit will have a coil for cooling and a heat exchanger.
