The humid and blistering days of summer are upon us, and people all around
the West Palm Beach area have gone to switch on their air conditioners.
However, if you’ve found your thermostat sitting there with a blank
screen, you know the feeling of dread. When no amount of button-pushing
can get your system to respond, there comes the thought of whether or
not your air conditioner has died on you.
Well, there’s some good news: a thermostat that’s completely
blank and non-responsive isn’t usually a sign that your air conditioner
has given up the ghost. In fact, more often than not the problem is actually
with the thermostat itself. On this blog, we’ll go over what can
cause a thermostat to go blank like this and whether or not it’s
possible to fix it on your own (which, yes, sometimes it is).
Did you know the thermostat on your walls could run on batteries? Most
people don’t realize this, but just because your thermostat is connected
to your wall and has wires running out of it doesn’t necessarily
mean it draws its power from your electrical grid. If the battery dies,
so does your thermostat and thus your ability to control your HVAC system.
There’s a pretty easy way to check if a battery is the problem: simply
pop open your thermostat and replace it. While we can’t necessarily
tell you how to open your exact thermostat (there are thousands of different
models… far too many to list here), you can find out how with a
simple internet search if you’re not sure. Just note the model number
of your thermostat and run a quick internet search for the “user’s
manual” for it. Once you’ve popped the thermostat off the
mount, pull the old battery out and stick in a new one. Most thermostats
require either a nine-volt cell, AA, or AAA battery. Once you replace
the battery, your thermostat should come right back to life, giving you
some much-needed relief and full control of your air conditioner again.
Tripped Circuit Breaker
If your thermostat
does run on electricity from your walls, then odds are you won’t find
a battery when you pop the front off. When this is the case, then you
may have tripped the circuit breaker or blown the fuse that keeps that
particular electrical circuit going. This is not all that uncommon during
summer time, when air conditioners are running heavily for hours on end,
drawing an immense load of electricity.
To fix it, simply find your fuse box or circuit breaker panel and then
replace the fuse that’s blown or reset the breaker back to the “on”
position. This should return your system to working condition and bring
your thermostat’s screen back to life. However, the fuse blows again
quickly or the breaker trips off after just a few minutes, keep it off
and call for repairs immediately. Odds are you have a much more serious
problem that needs urgent attention.
Like many other gadgets you might have, thermostats can and do eventually
die. When your thermostat dies, the screen will go blank and you won’t
be able to turn your system on. If replacing your battery doesn’t
solve anything and your breakers or fuses are all in good working order,
then most likely this is the problem you’re facing.
However, it’s also a blessing in disguise, as it gives you the opportunity
to make a small but tremendously impactful investment in your home’s
energy efficiency. Most modern thermostats are loaded with features that
encourage less energy consumption, better control over your climate, and
even give you the ability to connect to Wi-Fi or other networking protocols
so you can control it from a smartphone, tablet, or even the sound of
