Possible Causes of Problem
Power switch lamp is not lit when the power
switch is ON
Check that unit is plugged in and that the plug
is good.
Press the power switch to OFF and then back
ON. If the lamp remains unlit, reset the back
panel circuit breaker(s) by pushing in the reset
button(s).
Check the outlet to be sure power is available
to the unit.
Power switch lamp is the only one lit when
following the directions in the previous OPER-
ATION section
Using a screwdriver rotate the over-tempera-
ture thermostat stem completely clockwise (to
highest temperature settings). If unit still does
not heat up, the problem most likely involves
the heater status lamp. If the lamp is good,
check the heaters and heater wiring.
Convenience outlets are not powered when
unit is plugged in
Check that the other features of the unit are
functioning. If not, proceed with the first step
listed above.
Remove any plugs from the convenience out-
let(s). Press in the circuit breakers (located on
the back panel) to reset. If the circuit breaker
pops repeatedly, check the equipment that is
connected to the convenience outlet; check
wiring from circuit breaker to the convenience
outlet.
