TROUBLESHOOTING
SYMPTOM
1. Fireplace turns off and
will not turn on.
2. Flame is fixed
(unmoving).
3. Dim or poorly visible
flame or log set and
ember is not glowing.
POSSIBLE
CAUSES
Fireplace has
overheated.
Wiring may be loose
or the flame motor
may be defective.
Light bulb(s) burnt out
or wiring is loose.
WHO PERFORMS
CORRECTIVE ACTION
CORRECTIVE ACTION
Homeowner The appliance is protected with a
safety device to prevent it from
overheating. If the fireplace should
overheat, a thermal switch will
disconnect power to the unit and
will not come back on without
being reset. Reset it by turning
the main power switch off and
waiting 5 minutes then turning it
back on.
Qualified Service Technician Inspect all wiring for loose
connections. If the wire
connections are good, replace the
flame motor.
Homeowner Inspect all wiring for loose
connections and repair or replace
if necessary. Inspect light bulbs
and replace if necessary.
4. Flame sputters. Flame motor is
defective.
5. Remote control does not
work.
6. Circuit breaker trips or
fuse blows when the unit
is turned on.
Low batteries.
Unit switch and/or
wall switch in “ON”
position.
Improper circuit
current rating.
Qualified Service Technician Replace flame motor.
Homeowner Replace AA batteries in remote
control. If problem persists, there
may have been a loss of power to
the unit as a possible result from a
power failure (i.e. breaker tripped).
Turn off main power on/off switch
(see Figure 4) and/or optional wall
switch (if applicable).
Qualified Service Technician Check the house circuit to ensure
it is on a dedicated circuit with
proper Amp. rating. If the circuit
breaker continues to trip (or blown
fuses), inspect wiring for a loose
connection or a dead short. Repair
or replace wiring and/or
connectors as necessary.
