Thermostat Is Blank

Thermostat Is Blank

Our days are full of work and errands: Take kids to school, buy groceries, do laundry, prepare the speech for Monday’s presentation. The last thing you need is to worry about a thermostat that won’t turn on.

7 Reasons Why Your Thermostat Is Blank

Unfortunately, this predicament does happen on occasion. The silver lining is that sometimes, there is an easy solution.

1. It’s Turned Off

You may want to laugh about this one, but you’d be surprised at how often it happens. Maybe your spouse or one of your kids turned it off and forgot to turn it back on. Before assuming your AC has stopped working, check to see if the thermostat is on.

2. Tripped Circuit Breaker

Here’s another one of those really simple fixes. Cross your fingers and hope that this will do the trick. If you’ve never reset a breaker, you’ll notice that each switch has three settings: “On”, “Off” and the middle Neutral setting. When a breaker trips, the switch stays in the middle. Set it to “Off”, before setting to  “On”.

3. Dead Batteries

If steps one and two weren’t the issue, pop off the thermostat cover, take out the batteries and install a new pair. Easy peasy.

4. Dirty Wiring

While the cover is still off, check to see if there’s an accumulation of dust on the wiring. If so, use a soft brush or compressed air to clean them before putting the cover back on.

So far, so good, right? If you fixed it, voilá! Have a happy day! If you haven’t, this is when things start getting more complicated.

5. Blown Fuse

You’ll need a multimeter for this one. Walk outside your home, towards your AC condenser unit. Somewhere near it, on an exterior wall of your home, you’ll find the fuse box. Attach them (one at a time) to the multimeter, to see if they have any voltage left. If either one doesn’t, you can purchase a new one online or at any hardware store.

6. Wiring Issues

You’ll need to call an HVAC professional or an electrician for this one.

7. Mismatched Parts

Have you recently replaced either the inside or outside unit of your air conditioner? What about the furnace? All of these parts are designed to work together, and changing them piecemeal may cause compatibility problems later on.
