Problem
Solution
Heater’s airflow is
reduced.
Check for any objects that could obstruct airflow. If
the heater’s airflow is still diminished or has stopped,
please call Customer Service.
Heater stays on after
POWER is pushed.
The heater is cooling down, this is a normal function.
DO NOT unplug the heater until you no longer hear
the fan.
Heater fan still on 20
minutes after shut-
down.
This is most likely a defective fan relay. Please call
Customer Service.
Heater display shows a
line of dots.
After a period of inactivity, the heater will enter into
a “screen saver” mode to conserve power. When any
function key is pressed, the display will reappear.
Heater temperature
does not match central
thermostat temperature.
Refer to the Calibrating the Internal Thermometer
instructions in this manual for programming instructions
to match heater thermostat settings with your existing
wall thermostat.
Heater will not turn on.
Test the outlet to make sure there is power available
and then check the heater display for the flashing TIME
DELAY light. Press the POWER button to turn off the
timer and resume normal operation of the heater.
Heater doesn’t seem to
be getting hot enough.
Most likely, one of the ceramic elements is burnt out
or the connection to the element is bad. Call Customer
Service for help, the defective ceramic plate may need
replacing.
The power plug is
getting too hot.
There may be too many appliances running on the
circuit that the heater is on, including on other wall
plugs. Turn off any other appliances that share the same
circuit. The wall outlet may be old or worn, and is not
providing good contact with the plug. The wall outlet
should be changed. If the problem is not fixed, there
may be an issue with the house wiring not being able
to carry enough current.
The heater is noisy.
Check for obstructions to the fan blades. If there are
none, you have a defective fan. Please call Customer
Service.
