Are you getting a “Ground Fault” error after a few years?

 

It is very uncommon for a mat to fail over time. Because there are no moving parts and no leaking or freezing liquids, systems will last a very long time. However, if repairs are done to the floor, fixed furniture or any related area in the room, damage can be done to the cable and needs to be addressed. Common instances are trim work, tile repair, grout cleaning, and door stops.

If you get a ground fault error message you should perform a power cycle:

If the error message still persists after this video, it will be necessary to investigate further. It is not impossible that a slight cable damage was not spotted during the installation and reveals itself as a break or ground leak after a few weeks or months of operation. Again, this is uncommon, but possible. To further investigate be sure to gather the part number of the heating system installed and the system resistance readings. Contact Warmup for help along the way.
