TROUBLESHOOTING
Heater
doesn’t work
at all.
1. Supply connections
are loose.
2. Heater has tripped
one of its high-tempera-
ture safety shutos.
3. Heater has tripped
its secondary high-tem-
perature safety shuto.
4. Supply circuit is
faulty.
1. Turn o power at main disconnect panel. Inspect and/or tighten
all the wire connectors inside the heater and at any connection
points inside junction boxes or at the wall thermostat.
2. TO RESET: Turn power o at main disconnect panel. Allow 20
minutes to cool. Make sure heater is not blocked and is clean. Re-
store power. If the high-temperature safety shuto trips more than
once a day, replace the heater.
3. Replace heater.
4. Call a licensed electrician.
Breaker trips
immediately
after install-
ing heater.
1. A short circuit exists
in the electrical supply
wires or heater wiring.
2. Circuit breaker and
heater are not the same
voltage.
3. Circuit is overloaded.
4. Supply circuit is
faulty.
1. An incorrect connection in the heater or electrical supply wires
may cause sparking or arcing. Inspect all heater and electrical
supply wiring insulation for damage or call an electrician.
2. Double check the voltage of the heater to make sure it matches
the voltage of the circuit. Replace heater with a model that is 240
volts.
3. Use a lower wattage heater, or reduce the number of heaters on
the circuit.
4. Call a licensed electrician.
Heater blows
cold air or
doesn’t get
hot.
1. Element has failed.
2. Only one side heats
and the other side
has tripped one of its
high-temperature safety
shutos (Model CST
only).
1. Replace heater.
2. TO RESET: Turn power o at main disconnect panel. Allow 20
minutes to cool. Make sure heater is not blocked and is clean. Re-
store power. If the high-temperature safety shuto trips more than
once a day, replace the heater.
Heater
smells after
installation
or not being
used.
1. Odor from element
manufacturing process.
2. Dust or lint inside the
heater.
3. Supply connections
are loose.
1. In a new installation, some smoking may occur as the element
initially burns o residue from manufacturing. It typically goes away
within several hours.
2. Clean heater (see “MAINTAINING YOUR HEATER” on page 8
for instructions).
3. Turn o power at main disconnect panel. Inspect and/or tighten
all the wire connectors inside the heater and at any connection
points inside junction boxes or at the wall thermostat.
Fan/motor
doesn’t spin
or spins slow.
1. Circuit breaker is 120
volts and heater is 240
volts.
2. Defective motor or
motor out of alignment.
1. Double check the voltage of the heater to make sure it matches
the voltage of the circuit. Replace heater with a model that is 120
volts.
2. Replace motor.
Heater
doesn’t turn
o.
1. Thermostat is de-
fective.
2. No thermostat
hooked up to control
heater.
3. Incorrect heater watt-
age for room size.
1. Replace thermostat.
2. A thermostat is required for all Com-Pak heaters. Purchase a
built-in or wall thermostat for your heater.
3. Install higher wattage model or additional heaters if circuit
allows.
High-temperature safety shuto
All Com-Pak heaters come with built-in high-temperature safety shutos that stop electricity flowing to
the heater if it gets too hot inside. See TROUBLESHOOTING below if you’re experiencing problems
with your heater.
