Troubleshooting Guide
Symptom
Probable Causes
Corrective Action
A. Circuit breaker trips.
Circuit breaker under-sized
Circuit length too long
Start-up temperature below design temperature
Re-size the circuit breaker and feed wiring according to
instructions.
Turn on/re-set.
Defective circuit breaker
Replace the circuit breaker
Connections or splices may be shorting out.
Physical damage to the heating cable.
To confirm that heating cable is damaged, test the
insulation resistance according to the procedure in
“Electrical Testing” on Page 15-16.
Locate and repair incorrect connections or splices.
Locate and remove damaged sections of heating cable.
To locate shorting problems, follow these steps:
1.
Visually inspect the power connection, splices,
and End Seals for proper installation.
2.
Check for visual indications of damage to the
heating cable.
3.
Look for damage at entrances to downspouts,
around eaves and valley areas.
4.
If at this point you have not located the
problem, you will need to begin isolating
sections of the heating cable to find the
general area of damage. For example, cut the
circuit in half and, using a megohmeter, test
both halves of the circuit to find the damaged
section. Then remove the damaged section of
the heating cable.
Bus wires in contact with each other.
Cut off the End Seal. Re-cut the heating cable end and
install a new End Seal.
Excess moisture in connection boxes or splices.
Dry out and re-seal connections and splices. Test with a
megohmeter per “Electrical Testing.”
Nick or cut in heating cable or power feed wire with
moisture present.
Locate and replace damaged power feed wire.
Using a 5-mA ground-fault protection device.
Replace circuit breaker with 30-mA ground-fault protection
device.
Controller not wired correctly.
Check controller’s wiring instructions.
B. Power output is at zero or appears low.
Low or no input voltage.
Check voltage and correct.
Circuit is shorter than design shows because splices or
tees are not connected, or the heating cable has been
severed.
Check length of heating cable installed. Check all heating
cable splices and tees. Check at End Seals for continuity.
Improper connection causes a high-resistance
connection.
Check and fix heating cable splices and tees.
The control thermostat is wired incorrectly.
Check and re-wire controller.
