Besides, do all Trane thermostats have batteries?

Not all thermostats use batteries; many are wired into the electrical system of the house. If you have a unit that uses battery power, remove the front plate from the wall plate and change the batteries to see if this brings the thermostat back to life again.

One may also ask, can a thermostat work without batteries? A 24 volt C (Common) wire provides power to thermostats that do not use battery backups. Low batteries in digital thermostats are a common cause of issues preventing the heating and cooling system in your home from running.

Considering this, what type of batteries do thermostats take?

Wall thermostats typically use AA or AAA alkaline batteries or 3V button-style lithium batteries. The battery of the thermostat keeps your programming saved and prevents your heating and cooling control system from turning off when the power goes out.

Can a bad thermostat cause AC not to work?

Under most circumstances, a bad thermostat will not have any effect whatsoever on the air conditioning system. The AC system is a completely separate entity; the only connection it has to the engine is at the compressor pulley, which derives its power from the crankshaft.

How long do thermostat batteries last?

Some batteries can last as long as 5 years while others might not make it 3 months. Even if your thermostat is hardwired, it will probably have a back-up battery that will need to be periodically replaced. But don't be upset—the back-up battery allows your system to work even if there is a glitch in the power system.

Why is my thermostat using up batteries?

The simplest answer is also the most likely: The thermostat is old or just faulty. The temperature settings you program into a digital wall thermostat don't impact battery usage (e.g., turning down the air conditioning in the summer won't save the battery life of your thermostat; you'll just save on your energy bills).

What causes a thermostat to lose power?

The power is out or a circuit breaker has tripped
The power loss could also be the result of a tripped circuit breaker that powers the air conditioner or heater. Many thermostats run on low voltage sent from the transformer on the HVAC system; if the transformer loses power, so will the thermostat.
