Troubleshooting Your Thermostat Issues

thermostat repair

Having a faulty or broken thermostat can cause your homes cooling and heating system not to come on, but there are ways to diagnose the problem when it happens. A typical unit looks like a remote control, and it kicks on your cooling and heating system when you desire to use it. There is nothing worse on a hot summer day than realizing your home just isn’t getting to the desired temperature you want. Your first instinct might be that there's an issue with your HVAC system, but don’t panic — it could just be your thermostat!

Common Thermostat Issues

If you are finding any of the below problems, here’s how to know it’s just a quick fix to your thermostat:

  • The AC or Heat is Constantly Turning On. Though the cause of this issue can often lie with your system itself, this could often be a thermostat problem. If you notice that your thermostat has excess sunlight just shining directly on it, it might be time to either invest in some new curtains or find a new location to place it. Placement is key, and you’ll want to keep your thermostat away from windows and doors, far from the kitchen, and a reasonable distance away from any sunlight. A wrong location can not only cause the system to go on continually — it can lead to inaccurate readings, too.

  • Your System Won’t Stop Running. The sound of your HVAC system continually running could be a bit concerning, but it’s probably less of an issue than you realize and could just be the fan that you're hearing. Your fan setting could be set to “Fan On” instead of “Fan Auto.” By switching it to auto, the fan will only be running when your air conditioning is on. For a more energy efficient home, this is a must!

  • The Wiring Isn’t Right. If you’ve tried every setting in your thermostat, but your system still won’t turn on — your wiring could be to blame. Whether it’s loose or a disconnected wire, there could be a connection issue to your HVAC system. You might be able to fix the problem with just a simple tightening or wiring replacement.

How to Fix Thermostat

If you find yourself in a situation where it is not functioning properly, you can use this quick and easy steps to troubleshoot the problem.

1. Check Your Humidistat

First, you would want to check the humidistat, if it is set to the away setting the thermostat may appear blank until it reaches the level set on the humidistat. Set this to the home setting and the unit should work correctly.

2. Check The Batteries

If this doesn’t fix your problem, you would need to check the batteries in the unit. First, remove the cover usually it will just pull straight off of the wall then you can see the inside where the batteries are and what kind you will need to replace them. Please, be careful not to touch any of the components inside the unit, all of its these points need to be aligned and make proper contact inside and not get bent.

Very carefully align the cover and then snap it back on. Once the cover is back on, you should see it start working again.

3. Check for a Possible Breaker Issue

If there’s still an issue, then check the breakers to the AC system or reset them.
