Corrective Action
This is normal operation for the unit. During start-up, the unit is
preparing warm air.
• In heating mode, ice/frost is built up on the coils when the
outside temperature falls.
• Defrost mode removes a layer of frost from the coil.
• Wait until this operation is completed. It takes approximately
15 minutes.
Heating capacity of the unit may not by sufficient to effectively
warm air.
• Check to see if timer function has been set to turn off at a
designated time.
• Check timer settings and make adjustments as needed.
• Auto restart is the default setting and the system is rebooting.
• If you experience frequent power failures, it is helpful to
verify that the system is set to auto restart so the unit can
power up quickly.
Wait until the auto clean mode has finished and then turn off
this feature.
These modes do not allow you to adjust the fan speed. Change
