Furnace thermostat error issues
Today, many homes get their backup source of heat from oven hoods that vent into the house. These require both a low-limit switch and a high-limit switch to be working in order for the system to work correctly.
This switch is independent of the HVAC but this does not mean it does not control its own issues. A gas furnace with a faulty thermostat may serve as a warning of another issue like problems with the tank or combustion chamber
What do we tell a customer when such an issue is found?
This means that you need to find out which electrical circuits, mechanical components, and unknown factors are at fault first. Is it due to overload, or is it due to an installation error?
Regardless of the cause of this error problem, there are still two possible solutions: upgrading or repairing. Upgrading may involve replacing current outdated appliances with newer models while repair will likely involve locating and fixing any faulty components in the circuit board that might not be compatible with newer

With an error code on their furnace, many homeowners have to work out what the number refers to in order to find the problem.
The broken air conditioner will then report a “C-3” error code that you might be able to research and figure out what it means but newer furnaces not so much… The best way to find out why your furnace is telling you is kind of like a truck trying to get someone’s attention with “BEEP, BEEP.”
Every digit in the error message corresponds to one of 6 different possibilities that may be wrong with your home heating system and all possible solutions are given for each one. These errors can range where the furnace blower motor is not working, thermostat settings are incorrect or need recalibration, control board needs to be replaced.

A furnace’s thermostat is not functioning properly, but what does it mean for you? Gas furnaces will call for heat when the set temperature is not too low and the furnace is running. Problems with the furnace thermostat could be due to a worn or defective electrical switch.
Homeowners know the words “feedback” or ‘error,” they might see on their thermostat, but they have no idea what that might be meant to communicate. Some signs of issues causing an error include if it takes much longer than normal to start up your gas furnace, if your home’s temperature becomes erratic, or if it has gone as far as shutting off our heating system altogether. If your home has older features like incandescent fixtures, change can affect how quickly or erratically heating happens throughout space in winter.
