Braeburn Thermostat Not Working – Let’s Fix It

Braeburn Thermostat Not Working –¬†Getting ready for summer is fun but also a job we do every year. We check pipes, clean drains, and look at the heating system. While doing this, I saw my thermostat wasn’t making things cold.

A few months ago, we started using a Braeburn thermostat. I didn’t know how to fix the problem. After looking at some books and help papers for a few days, I learned how to make the thermostat work.

So, here’s how to make a thermostat cold again.

If your Braeburn thermostat isn’t making things cold, press the RESET button. Then, see if your thermostat’s AC filters are old and need to be changed. Make sure there’s no liquid coming out from it.

Lastly, make sure your Braeburn thermostat has enough power to make things cold.

How to Reset Braeburn Thermostat?

Setting your thermostat again is easy. There’s a RESET button in a tiny hole on the front of the thermostat. Push this button with a toothpick or small pin.

Most Braeburn thermostats have the same button, so you don’t need special instructions for different models.

But remember, when you do this, all your chosen settings, like turning it on or off at certain times, will be gone.

Change the AC’s Air Filters:

The thermostat might not work right if the filters are dirty. If your filter has a lot of dirt, it won’t cool very well.

Here’s how to change them:

  • Look for the air filter. It’s usually close to the thermostat.
  • Open the cover by undoing the clips. Behind it, you’ll see the air filter.
  • Reach in and grab the filter to pull it out.
  • Check how it looks. If it’s dusty and a dark color, get a new one. If it’s kind of white, it’s good for a while longer.
  • On the side of the filter, there are arrows. Make sure they don’t face you or out. They should face the wall, so air moves right.
  • Slide the filter back. Start at the bottom and then at the top. Push to make sure it sits right.
  • Put the cover back on and close the clips.

Check for Coolant Leaks:

There might be a few reasons why it’s not cooling well, and one could be a leak in the coolant. If your AC is new, maybe it wasn’t set up right or there’s something wrong with how it was made.

As time goes on, the HVAC parts might not work as well. Another reason is if something damaged the outside HVAC part.

Rust can cause a coolant leak too. A kind of acid eats the metal in the HVAC, and then coolant goes into the air.

If you see these things, your coolant might be leaking:

  • The system is releasing warm air
  • The system is producing hissing sounds
  • The coils have frozen

Fixing this is hard for regular people. It’s best to ask a technician who knows about AC repair to help.

Check the Power Supply to the Thermostat:

If the thermostat has no power, it can’t work. But you can’t just look at the lights to see. The lights and the control part use a battery.

Here’s how to see if your thermostat has power:

  • Make the temperature really low and move the ‘FAN’ button from ‘AUTO’ to ‘ON’. If there’s no change in temperature or you can’t hear the fan, it might not have power.
  • To check better, try the bypass test. Take off the cover of the thermostat. You’ll see a red wire (R) and a green one (G). Take them out and switch their places. If the fan starts, then it has power.
  • If you have a tool at home called a multi-meter, use it. Set it to 24 Volts AC. Touch one part of the red wire. Touch the other part to the green, yellow, or white wires. If the number is between 22-26, it has power. If it says 0, there’s no power.

Contact Support:

If none of these steps worked, the problem could be serious. Your heat pump might be broken, or you might need to get a new one.

The best thing to do is to contact tech support. Ask for a technician who knows about fixing central air conditioning systems. You can either send them a message explaining your problem or call them directly.
