Troubleshooting Guide

If problems arise with the Tapemat to perform electrical work, it is highly recommended that
a qualified, licensed electrician be hired.
Although this troubleshooting guide is provided to assist with problems experienced with a
floor heating system, results are never guaranteed. TapeMat does not assume any liability or
responsibility for damage or injury that may occur from using this guide. If problems with the
system persist, call the manufacturer.
Any electrical troubleshooting work should be performed with the power removed
from the circuit, unless otherwise noted.

needle) was used to take the reading.

The multi-meter should typically be set to the 200
ohms (200Ω) scale. For mats with resistance range
higher than 200 ohms on the nameplate label, set the
meter to the 2000 ohm (2kΩ) scale.
Measure mat resistance. Check for both "open circuit"
and "short circuit" as detailed earlier in this manual.
If damaged, record resistances between all wires and
contact the manufacturer.
Check for loose wire connections. Reset the GFCI on the
control or circuit breaker. If it trips again, check for a
short circuit in the mat as detailed earlier in this manual.
If mat is damaged, record resistance between all wires
and contact the manufacturer. If mat is not damaged,
replace the GFCI control. Also see "GFCI conflicts" below.
Measure "line" voltage, then measure "load" voltage.
120 VAC mats have black and white power leads. 240
VAC mats have black and blue power leads.

hours of heating, the floor is not warmer to the touch,
check for mat damage (see "Mat has been damaged"
above). A clamp-on ampmeter may be used to verify
the amps are correct to each mat.
