Is Your Furnace Acting Up? These Tips Will Help You Confirm Or Rule Out Thermostat Problems
The furnace has multiple parts that all need to operate efficiently if the furnace is to continue heating your house as usual. That is why you need to diagnose each of your heating system's parts if it is not producing heat as usual. When it comes to the thermostat, here are the simple diagnostic measures to take:
Confirm That It Is Switched To "Heat"
In many cases, people think that their thermostat is malfunctioning while, in the real sense, it is not just properly set. Therefore, the first thing to confirm is that the thermostat is set to "Heat" instead of "Cool." Otherwise, you will be wondering why your furnace isn't working while you are the one who hasn't triggered it on via the correct setting.
Confirm That the Temperature Setting Is Right
In addition to confirming that the thermostat is set to "Heat," you also need to confirm that the thermostat has the right temperature setting. For example, the furnace will not be triggered on if the thermostat temperature setting is the same as the room temperature. To test if this is the problem, turn up the thermostat a few degrees to see if the furnace is working.
Confirm That the Right Date and Time Is Set
If you are dealing with a programmable or smart thermostat, then you should also confirm that the time and date setting is correct. It might be that your furnace is not working because it is using the wrong settings or readings from the thermostat. This can easily happen due to an error in the programming.
Confirm That the Batteries Are Not the Problem
Furnace thermostats have two sources of power, the mains and batteries. The batteries help maintain the memory of the thermostat (such as the programmed settings) and help the thermostat continue operating even during blackouts. Therefore, if your furnace or thermostat is acting up during a blackout, replace the batteries with fresh ones to confirm or eliminate battery issues.
Confirm Thermostat Wire Continuity
It may also be necessary to confirm that the thermostat wires are firmly connected to it and have continuity to the furnace. This is particularly necessary if recent events, such as a remodeling project, might have interfered with the wires' continuity. Just follow the wires from the thermostat to the furnace to check if this is the issue.
Hopefully, the problem will turn out simple and you will be able to fix it. If that doesn't happen, however, you can always consult a technician, such as at AIR PRO SERVICES, for further diagnosis and solution.
