Listed below are some possible reasons why it is not working and how to troubleshoot common underfloor heating problems.

Temperature Sensor

If the thermostat displays strange readings to normal, the underfloor sensor is perhaps faulty. Professional underfloor experts always install a second-floor sensor as a backup to the initial sensor. After that, if the floor sensor happens to become damaged, it would not be a major job to change the sensor is used by the thermostat. In case you do not have a backup sensor, you will then have to install a new underfloor sensor. You can either dig into the grout lines or dig up a tile so that you can position it in an adjacent manner to the underfloor heating mat.

Thermostat

Try setting the clock back to the factory settings to see whether your thermostat is faulty or not. If the problem persists, you then have to change the thermostat.

   Many repairs are steadily becoming necessary due to accidental damage of the electric cable. Fortunately, these kinds of failure show you know the exact spots where the break is for you to be able to fix it with a cable repair kit. Most electric underfloor heating mats are manufactured in the same way. This means that the break in the cables can be easily resolved by using a repair kit.

He would utilize various part of equipment like a thermal imaging camera to find the source of the failure. Upon the identification of the problem, he may simply dig up tile above the source and fix the break. You can then schedule a tile expert to fit a replacement tile or do it yourself. Do not forget to use grout and a flexible adhesive.
