My SunTouch Product is Not Working – What do I do now?

Floor heating system not working? No worries – it can be fixed and we can help. It doesn’t happen often, but floor heating systems can be damaged. Stuff happens, but you have come to the right place. Even if you don’t know what happened we can usually help you figure it out.

New Installation Troubleshooting:

The floor is closed and I know where the damage is.

  1. Carefully remove tile or floor covering to expose the break.
  2. Repair the damage following the instructions included with the repair kit.

I’m not sure why my floor stopped working, I need more help…

Is  the Thermostat the problem? If you haven’t ruled out the stat? Start there .

Thermostats cannot be repaired in the field, only replaced, as there are no batteries or other serviceable parts. Always replace BOTH parts of the thermostat – the base which is mounted to the wall and connect to power AND the faceplate which is attached to the base. Replacing only 1 piece will not solve your problem.

If you have ruled out the thermostat, then we’ll have to dig a little deeper.

Did your floor heating system stopped working after work was done in the room or to your floor (tile replacement, new toilet, tub or cabinet, drilled holes, etc)? That is the prime suspect. Keep reading for further advice.

I know the wire is cut or pinched, but I do not know where.

We have tools to help you trace the location of a break – but you can often save time and money if you know someone penetrated a floor that was previously heating fine, and go right to that spot to check for damage, so ask others and see if anyone remembers what might have happened. 

Was any tile removed or replaced? That is a this is the likely location of a break.The heating elements may have been damaged during the repair or other work. While it is possible to remove tile without damaging the floor heating elements below, this is frequent source of damage to the wires. Click here for tile removal tips

Tip – If thinset is not fully cured, you may be able to add a little water in grout joints and carefully pry up a tile.

The Heating Wire was Cut and the Floor is Still Open. I Know What Happened & See the Damage

This is an easy one!

Read the instructions, then order a repair kit. You need a few tools, including a heat gun. SunTouch Heating Wire Repair Manual (Mat & WarmWire)

Order a repair kit – each kit has the complete instructions found above – Heating Wire Repair Kit for SunTouch Mat or WarmWire(same kit)

The wire is damaged near the end…Here you have 2 choices

If it’s the last few feet, you can cut the wire at the break and perform an end splice – End Splice Repair Instructions

If you want to preserve the last few feet of heated area, get a repair kit and Follow repair instructions above – Purchase a power lead repair splice kit

Power lead repairs if the power lead is cut or damaged.

You’ll need a SunTouch/Warmwire power lead repair kit (this is a kit only for the power lead, not the heating wire)

If you have to remove tile, TURN OFF THE POWER first, then connect your loudmouth or multimeter first. Click here for tile removal tips (Tip: If you have to remove tile, connect your loudmouth or multimeter)

A Fault Finder may help find a break in a heated floor that is not working for SunTouch mats or WarmWire – Loudmouth Monitor Alarm

    I have a break in a sun touch floor. We do not know where the break is. What options do I have besides removal of the entire floor ?

  • johnny Dwain Houston says:

    Thermostat shows temp at 67 but will not heat up to programmed temp of 80. Thermostat is receiving electricity as the faceplate is lit up. Not sure what to do next.
