Symptom
Possible Cause
Corrective Action
The IFT -RC400 displays the
following message on-screen:
Appliance safely disabled.
Call dealer for service.
In addition the LED indicator on
the IFT-ECM will flash twice red
and once green indefinitely.
Ignitor wires (orange) or flame
sense wire (white) is shorted to
chassis ground.
Verify that pilot sense and ignitor leads are not shorted to chas-
sis ground and the protective covering has not melted or is cut.
Replace pilot if necessary.
The IFT-ECM is unable to sense
flame due to contamination on
flame sensing rod.
Measure pilot sense lead resistance. If more than 1 Ohm,
clean flame sensor rod with fine steel wool and measure re
-
sistance again. If resistance still > 1 ohm, replace pilot.
Ignitor and sense wires are
incorrectly wired.
Verify that the sense lead (white) is securely terminated to the
"S" terminal on the IFT-ECM, and that the ignitor lead (orange)
is terminated to the "I" terminal on the IFT-ECM.
Pilot appears to be 'missing'
sparks from the ignitor.
Verify that pilot sparks 8 secs ON, 2 secs OFF, and discharges
consistently between the hood and the ignitor electrode. Verify
spark gap is 0.095 to 0.135 inches, and adjust if necessary.
The IFT-RC400 does not pair or
unpair from the IFT-ECM.
The IFT-ECM is not connected
to its power source.
Verify the IFT-ECM is connected to power and the three posi-
tion switch is set to REMOTE. If operating from the battery
backup, ensure that all four batteries are NEW.
Noisy radio environment is
preventing the IFT-ECM and
IFT-RC400 from communicating.
The IFT-ECM and IFT-RC400 operate on the 915MHz radio
band. Allow up to 10 minutes for the IFT-ECM and IFT-RC400
to establish contact. If the problem does not get resolved try
powering OFF and ON both the IFT-ECM and IFT-RC400 and
repeat the pairing process.
The IFT-RC400 displays the
following message on-screen:
“Remote Control Communication
Error.”
No power to Appliance
Verify home circuit breaker is on and master reset is on (if
equipped).
Power Outage
Check power to appliance or if the IFT-ECM battery backup is
being used, install four (4) new AA batteries in backup.
IFT-ECM Mode
Verify selector switch in “Remote” mode.
IFT-ECM Power
Verify the IFT-ECM connected to AC adapter and AC adapter is
plugged into the Junction Box.
IFT-ECM no longer paired to
RC400
Follow instructions on pairing IFT-RC400 to the Electronic Con-
trol Module (IFT-ECM).
The IFT-ACM does not respond to
commands from the IFT-RC400.
IFT-ACM was newly installed and
not paired.
Make sure that the pairing procedure has been followed espe-
cially if the IFT-ACM was newly installed.
The power cord between
IFT-ACM and junction box is
disconnected.
Make sure the power cable is properly inserted into the IFT-ACM
and the junction box.
IFT-ACM and IFT-ECM are not
latched.
Check the connection between the IFT-ACM and IFT-ECM by
making sure they are latched together.
IFT-RC400 display the following
message on-screen: Call Dealer
Error: Fan
Convection blower malfunction.
Using an RMS voltage meter, check the voltage coming out of
the fan port on the IFT-ACM or IFT-PACM 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 or IFT-PACM is
blown.
Using an RMS voltage meter, check the voltage coming out of
the fan port on the IFT-ACM or IFT-PACM 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 or IFT-PACM is not
responding to IFT-RC400.
‘If used with an ACM, ensure the ACM has 120VAC power. If
required, re-pair the RC400 to the ECM. If used with a PACM,
ensure the PACM has 120 VAC power. Then power cycle the
ECM to OFF and back to REMOTE
Fan is not plugged into IFT-ACM.
Check wiring and connections.
Spade connectors are miswired.
Some fans may be connected to the IFT-ACM using spade con-
nectors. For safety, turn off the power to the appliance and check
to see if the wires on either end of the spade connector do not
match in color as they might be miswired.
