Thermostat Not Working? Common Causes and Fixes for Kent Homes

When your thermostat is not working, it can cause heating issues, discomfort, and even increased energy bills. Whether you’re in Medway, Canterbury, or Sittingbourne, this guide will help you troubleshoot and fix the issue—plus know when to call in the pros at Plumble.

How to Tell If Your Thermostat Is Not Working

Wondering if your thermostat is faulty? Here are key signs:

  • No heating despite system being on
  • Room feels colder or hotter than the set temperature
  • Unresponsive or blank display
  • Radiators not heating but boiler is active

If your boiler is working but rooms are still cold, your thermostat might be the problem or it could be your ZONE VALVE.

Why Your Thermostat May Not Be Working

1. Dead Batteries in Your Thermostat

Most wireless thermostats run on batteries. Dead batteries are one of the simplest reasons your thermostat isn’t working.

2. Thermostat Settings Changed or Reset

Check if the heating mode, timer, or temperature settings have been altered—especially after a power cut.

3. Loose or Damaged Wiring

Old or frayed wiring inside the thermostat can lead to connection loss. This is a common cause of a thermostat not working.

4. Poor Placement Affects Thermostat Performance

Is your thermostat near a radiator or a draughty window? Bad placement can lead to inaccurate readings and affect your entire heating system.

5. Outdated or Incompatible Thermostat

Older models may not be compatible with newer boiler systems. If you’ve recently had a new boiler installation, your old thermostat could be the issue.

DIY Fixes for a Thermostat That’s Not Working

Warning: If unsure, always contact a Gas Safe registered engineer.

  • Replace the batteries
  • Double-check settings and timers
  • Reboot the thermostat and boiler
  • Clear any dust or blockages

If you still have a thermostat not working issue, a full replacement might be necessary.
