temperature.
The room
temperature has
reached the
temperature set at
the thermostat.

too low.
A Name You Can Trust
Solution
Set the desired
temperature higher than
the current temperature to
restart the heater.
This is normal. The heater
will restart once room
temperature is lower than
set temperature.
Place the heater in upright
position and check for any
obstructions. If you find an
obstruction, turn the
heater off. Unplug the
heater and wait at least 10
minutes for it to cool
down. Carefully remove
the obstruction. Plug the
heater in and restart it as
described in the
OPERATING INSTRUCTIONS
section. If you still notice
the same problem, remove
the plug from the outlet
and contact the NewAir
Customer Support
Department.
Close the window. Turn on
the main heat source of
the room and possibly use
more portable heaters.
Increase the temperature
or power setting.
