Problem

warm when
the system is
turned on
Potential cause
The heating
ribbon has been
damaged
The electrical
connections
were
mismatched
The GFCI has
been tripped
Thick

Solution
Check resistances of the mat in question. Compare
them to the resistances recorded earlier, and with the
resistances stated on the label.
Check all wiring around the parallel connections, breaker,
and any other connections points. Con
fi
rm the correct
voltage is being supplied to the system.
Check for a trip indicator light on the GFCI control. Check
all wiring and for loose connections.
Some electric devices including electric motors can
create interference for GFCIs, creating false-trips. If the
Warmset mat system shares a circuit breaker with any
other devices, move the system to its own breaker.
If the breaker trips again after these steps, replace the
GFCI.
If a thick stone or concrete
fl
oor covering is installed, the
system might take an extended period of time to heat
the surface. Ensure enough time has passed after the
system has been activated.
Note
If you experience any problems with the installation of your
Warmset system, please refer to this section. If the system was not
originally installed by a licensed electrician, consultation with one
is recommended. If problems persist, please contact Warmset Ltd.
All troubleshooting work should be done with the power turned off.
