Hey everyone, my central heating unit was showing a T1 error code and wouldn't turn on. After some digging, I found out it's a common issue with the thermostat sensor. The fix is pretty simple: you just need to gently pull the thermostat off the wall, unplug the little wire connector for a minute, and plug it back in. It resets the sensor. Worked for me! Hope this helps someone else.

You are a lifesaver! This just happened to me and I was about to call an engineer. It worked!
