Troubleshooting Chart - Cadet CB103T Manual Del Propietário

Maintenance As Needed, or every six months minimum.
WARNING! Before removing grill, turn the electrical power off at the main disconnect
panel (circuit breaker or fuse box). Lock or tag the main disconnect panel door to prevent
someone from accidentally turning the power on while you are working on the heater.
Failure to do so could result in serious electrical shock, burns, or possible death.
WARNING: Any other service not detailed in this Owner's Guide should be performed by an autho-
rized service representative.
1. It is important that you verify power has been turned off and no
power is going to the heater before proceeding. Circuit breakers
are often not marked correctly and turning the wrong breaker off
could mean electricity is flowing to the heater, even if the heater
does not appear to be working. If you are uncomfortable working
with electrical appliances, unable to follow these guidelines, or do
not have the necessary equipment, consult a qualified electrician.
2. Once you verify the power has been turned off correctly, pro-
ceed to the next step.
3. Remove thermostat and timer knobs, screws and take off grill.
4. Wash grill with hot soapy water and dry.

ELECTRICAL SERVICE PERSONNEL.
1. Verify that supply voltage matches the heater rating.
2. The total amperage of all heaters on a branch circuit must not be more than
80% of the amperage rating of the circuit breaker and supply wire ratings. Use a
lower wattage heater, or reduce the number of heaters on the circuit.
3. Shorted supply or heater wires may be accompanied by severe sparking.
Inspect all supply and heater wiring insulation for damage. Do not reset the circuit
breaker until all electrical shorts have been repaired.
4. Replace the circuit breaker.
1. Allow a few moments for element to reach operating temperature.
2. Verify that supply voltage matches the heater rating.
3. Replace element.
1. Close doors and windows. Provide additional insulation, or install a higher
wattage heater or multiple heaters if necessary. (If your circuit is rated for more
capacity.)
2. Wait for the timer to time-out or turn the timer counterclockwise to `0' (The timer
overrides the thermostat setting). If heater continues to run, adjust thermostat to
its lowest setting. If heater continues to run (allow two minutes for thermostat to
respond) the thermostat requires replacement.
1. Clean heater (see "MAINTAINING YOUR HEATER" section above for instruc-
tions).
2. Turn off power at circuit breaker. Inspect all supply and heater wire connections
to make sure nothing is loose or poorly connected. Secure or reconnect all loose
connections. Do not reset circuit breaker until all connections have been checked
and repaired.
1. Heater or fan motor requires replacement.
2. Remove obstruction and press heater reset button (after allowing the unit to
cool). Test heater operation—if reset button has been pressed (be sure to listen
and feel for a click indicating it has been reset), but heater does not run, heater
requires repair or replacement.
1. Adjust thermostat to a higher temperature until heater operates (See Problem
#5 if the problem persists).
2. Press the manual reset button (See "OPERATING INSTRUCTIONS" section).
3. Turn on the correct circuit breaker in the main disconnect panel.
4. Turn off power at circuit breaker. Check supply wire continuity and proper con-
nection to heater wires.
5. Repair or replace the heater. The entire heater, or any of its components may
be checked for continuity to determine the cause of any problem.
1. Clean heater (See "MAINTAINING YOUR HEATER" section for instructions).
2. Remove obstruction. Maintain a minimum distance of 6 inches from adjacent
surfaces, 4½ inches from the floor, and 3 feet for furniture or other objects placed
directly in front of the heater.
3. Remove obstruction, and press heater manual reset button (See "OPERATING
INSTRUCTIONS" section).
4. Replace heater assembly.
5. While holding fan (to avoid damage or bending), use a hair dryer
or vacuum on blow cycle to blow debris through the top element
(do not touch element).
6. Vacuum fan area without touching the elements.
7. Do not lubricate motor.
8. Replace grill and secure with screws. Replace thermostat and
timer knobs.
9. Turn thermostat to desired setting.
10. Turn power back on at the main disconnect panel.
