Yes, low batteries will affect your furnace/AC operation. Change the batteries to correct the issue.
i have a model 125u19 payne furnace i move the thermostat but nothing comes on in the furnace and the pilot light is lit
There could be several reasons why an electric furnace won't shut off, including a malfunctioning thermostat, a stuck relay, or a problem with the limit switch. It's best to have a professional technician inspect and diagnose the issue to ensure safe and proper operation of the furnace.
If a gas furnace continues to run past the set temperature, it could be due to a faulty thermostat that is not sensing the correct temperature, a problem with the furnace's control board, or an issue with the limit switch that is not shutting off the furnace at the right time. It is best to have a professional HVAC technician inspect and diagnose the problem to ensure safe and efficient operation.
To turn on a furnace without a thermostat, locate the furnace switch on or near the unit. Flip the switch to the "on" position to start the furnace. Keep in mind that without a thermostat, you won't be able to control the temperature or set a programmed schedule for the furnace to operate.
Yes, a thermostat is required for an outdoor furnace. I recommend going to http://www.buycheapr.com/us/result.jsp?ga=us11&q=outdoor+thermostats for discounted thermostat.
There is always a wall thermostat for regulating furnace heat.
Set thermostat to desired temperature; lets say, 70 degrees Fahrenheit, a few seconds will go by then the furnace should activate. Once the furnace heats the room to the set temperature the furnace should shut off.
Exactly what I am doing now. My furnace is old and ineffiecient so I bought a new, ineffiecient furnace. (80%) natuaral gas. I also bought a cooling coil that fits on top (upflow furnace) of the furnace. I bought a condensing unit that will go outside and be wired to the furnace and thermostat and connected to the coil with refriderant lines. All of this was less than half of what an installer quoted for just a new furnace! The new furnace is the exact dimensions of the old, so it is a plug and play situation. However, I need to have a licensed plumber make the connections, which then need to be inspected by the town. I have an EPA 608 certification to make the AC connections, but that must be inspected as well. I have to run a whole new circuit (220V) to the wall where the outside unit will sit. So for less than $2,000 I will replace my old junky furnace for a new split system furnace/AC system. I also replaced my old thermostat for a new digital programable thermostat for $49. This should save $ as you can program less heat or cool when everyone is at work.
The negative feedback system. It works much the way a thermostat works. When the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. Once the furnace has raised the temp in the room to the set level, the thermostat signals the furnace to shut off. It will continue to stay off until the thermostat signals that the temp has dropped again.
The power to the thermostat comes from the transformer in the furnace or air handler whichever you have. 1) the power to the furnace/AH is off, 2) the control fuse that protects the transformer is blown, 3) the transformer is defective, 4) the wire between the furnace and the thermostat got cut.
If the thermostat is open, the ohm reading will be O/L.
