TROUBLESHOOTING

WARNING. Only open the junction box if it is safe to
do so!
WARNING
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 Thermon Heating Systems,
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.

heater clearances are maintained and no debris is around
the heater or stuck in the fins.
3. Check all mounting hardware and ensure fasteners
are tight.
4. Replace the cover securely and turn on the
power supply.
