Error: Fan
Convection blower
malfunction.
Using an RMS voltage meter, check the voltage coming out of
the fan port on the IFT-ACM when the fan is set to highest level
on the IFT-RC400. If the voltage measured is close to 120V AC
then power down the appliance and install a new fan and verify
if the issue has been resolved.
Fuse in IFT-ACM is blown.
Using an RMS voltage meter, check the voltage coming out of
the fan port on the IFT-ACM when the fan is set to highest level
on the IFT-RC400. If voltage measured is closer to zero, then
replace the IFT-ACM itself
IFT-ACM is not responding to
IFT-RC400.
Follow steps listed in the first symptom.

120V AC then power down the appliance and install a new light
kit and verify if the issue has been resolved.

Using an RMS voltage meter, check the voltage coming out of
the lights port on the IFT-ACM when the lights are set to highest
level on the IFT-RC400. If voltage measured is closer to zero,
then replace the IFT-ACM itself.
IFT-ACM is not responding to
IFT-RC400.
Follow steps listed in the first symptom.
Lights are not plugged into
IFT-ACM.
Check wiring and connections.
LED controller is not
functioning.
Some appliances come with an LED controller that plugs into
the Lights port on the IFT-ACM. Verify the wiring and check

Error: Power Vent
Multiple causes.
Please refer to the troubleshooting guide that came with your
Power Vent.
Lights are blinking and/or fan
and Power Vent blowers are
fluctuating.
Poor quality of power from
local power station.
Check with customer if they are also noticing issues with
other unrelated appliances and if other lighting fixtures are also
blinking/dimming randomly. If so, install a surge suppressor be-
tween the hearth appliance and its power source.
IFT-RC400 display the following
message on-screen: Fan will turn
on within 3 minutes
Functioning as intended.
The appliance has a three minute delay timer before the fan is
turned ON. This allows the air surrounding the appliance to be
heated before being pushed into the room.
