SYMPTOM PROBLEM SOLUTION
Breaker trips
1. Short circuit 1. Find source of short. Trace heater circuit and verify the heater is wired properly.
2. Overloaded circuit 2. Reduce wattage in circuit. Refer to circuit sizing table for maximum wattage
3. Improper voltage 3. Verify the heater voltage matches the supply voltage.
Heater not working
1. No power 1. Turn breaker on. Turn thermostat on. Check that the breaker is positioned properly on panel bus-bar. A 2-Pole breaker
must be connected to both bus-bars (A&B phase) to produce 240V power.
2. Loose connections 2. Tighten wire connections.
3. Defective limit 3. By-pass the limit to test. If heater works, replace the limit.
Heater Smokes 1. Oil on element 1. It is normal for the element to burn off some light finishing oil used in the manufacturing process when first energized.
Open windows and allow room to vent until it stops, usually within a few minutes.
2. Needs cleaning 2. Remove any dust or dirt accumulation.
Room Temperature
does not match
thermostat setting
1. Thermostat affected by
another heat source
1. Sunlight or other heat sources can affect the thermostat. Move the thermostat to another location or remove the heat
source.
2. Improper calibration 2. Remove cover and adjust calibration screw.
Room Temperature
swings from too hot
to too cold
1. Defective or low quality
thermostat 1. Replace with a better quality thermostat. Anticipated thermostats are fairly accurate; an electronic thermostat is the best.
Your heat er will give you years of service and comf ort wit h only
mi nimum care. To assur e ef ficient operat ion f ollow t he simple
inst ruct ions below.
1. The user can perf orm some basic cleaning of t he heat er. All
ot her servicing is t o be done by qual ified service personnel.
2. Because of t he convect ion heat ing principle which depends
upon a circulat ion of air t hrough t he finned element , dust will
collect bet ween t he fins. The heat er should be cleaned regu-
larly f or maximum ef ficiency.
3. To cl ean heat ing element fins, first remove bot h wiring com-
part ment covers and t he f ront cover. Using a vacuum cl eaner
or compressed air, remove t he dust and lint from t he alumi-
num heat ing element fins while being caref ul not t o damage
t he fins.
4. The paint ed heat er cabinet may be cleaned using a sl ight l y
damp clot h. Do not use abrasive cleaners or waxes as t hese may
damage t he finish or leave a residue t hat will discolor.
5. Replace f ront cover (making sure it is lat ched in pl ace at
each element support bracket and at each end) and t wo wiring
compart ment covers (using t he t wo screws provided), rest ore
power and check heat er f or proper operat ion.
TROUBLESHOOTING CHART FOR BASEBOARD HEATERS
