Things to Do if Your Thermostat is Reading the Wrong Temperature

If you have a thermostat that is reading the wrong temperature, you do not need to worry. There are many simple things that you can do to fix this problem. This blog post will go over everything from what to do if your thermostat won’t turn on to how long it takes for a thermometer to change its reading.

The Fix

What not to do?

First, let us go through a quick guide as to what should not be done whenever you have a warning sign in your radiator thermostat.

  1. Don’t put any objects in front of the sensor or attempt moving its location of where it is installed in your house because this could cause damage and void warranties.
  2. Do not try turning up the heating too high as this could result in fire hazards within the unit, which may also lead them to be damaged beyond repair.

What to do?

Now that the precautions are well taken here of, here are the things that you should follow:

  1. Turn it down

If your thermostat’s setting is too high, the sensor may be reading a higher temperature than what you have set it at. In this case, turn down the heating or cooling unit and see if that fixes things.

  1. Remove the batteries

If your radiator thermostat has been exposed to water for an extended period before drying out entirely, there’s a chance that condensation might have gotten into the inner parts, which could cause damage as well! Try turning off power and then wait about 20 minutes. Afterward, remove batteries from their compartments located on either side of where they sit inside your device (if applicable).

  1. Blow out the moisture

Next, take off any backplates until you can access all internal parts. In this case, try blowing out any moisture you can see or feel gathered on the internal circuits and components with a hairdryer at its lowest setting.

  1. Clean up the corrosion

Make sure that your thermostat’s batteries are correctly installed and not corrupted! Corrosion can build up over time if they aren’t changed regularly, so try removing these from their compartments on either side of where they sit inside the unit (if applicable) and check for any corrosion. If you see some, use a cotton swab to clean it off with vinegar or rubbing alcohol before reinserting them back into place.

  1. Replace the batteries

While changing the batteries out, look at how old these are getting. Try replacing both alkaline ones and rechargeable options since new units like this tend to come with more advanced features such as Bluetooth capabilities, which could be causing issues within your system!

Check if your thermostat’s batteries are drained by turning it on and looking at the reading! If no display shows up, this can indicate that you need new ones installed before plugging in both electricity companies once they’ve been changed out.

  1. Contact a professional

The problem with a thermostat reading the wrong temperature can be tough to fix. It may not be an easy fix and might require professional attention from someone experienced in this type of work. If you suspect that your thermostat might be faulty, contact a professional to help with the machine’s replacement or repair.

If you live in a house with central heating or cooling, your thermostat should be reading at the right temperature within about an hour after following the above-mentioned steps. However, if you have a portable unit that uses batteries and may need to change them depending on how much it is used, then expect things like these to take longer before becoming effective!


A radiator thermostat is an important investment for the house. Something going wrong with your cozy home will definitely not feel right, isn’t it? So be aware and follow the above-mentioned tips and steps whenever you spot anything going wrong with the thermostat installed in your home.
