10.0 TROUBLESHOOTING
WARNING
ONLY OPEN THE JUNCTION BOX IF IT IS SAFE
TO DO SO!
10.1 These heaters contain a thermal fuse. If the
unit is not operating within proper constraints,
the unit may have overheated, causing the
thermal fuse to open. Check the thermal fuse by
disconnecting the power, opening the junction
box and measuring the resistance across the
terminals. If the resistance is infinite, the fuse
has been triggered and the unit must be sent to
CCI Thermal Technologies Inc. for repair.
NOTE: If your circuit contains a thermostat and the
ambient temperature is high enough to turn off the
thermostat, the measured resistance will be infinite,
this test will not check the thermal fuse.
