SERIAL NUMBER 14-000001 AND UP

No Power To IQ Control

**Maxi Heat 500IQ Controller does not turn on or has no power to the IQ box.**

❏ No power into the IQ controller will not activate the LCD screen for further

operation. Make sure the door on the outlet (heat out of burner) side is

open. The micro switch in the corner of the door activates power to each

screen. * Switch is a two pole switch, if one side fails then the other could

still open and provide power to the other screen.*

❏ Check the relay in the transformer box next to the controller (Example

"A"). Make sure connections are secure and the relay is functioning

properly.

❏ Check the heater element on top of the fuel water separator filter. If

element shorts then it will draw too much amperage and not allow the

screen to power up.

❏ If the IQ controller has 12 volts on the two wire ( example "B" below)

harnesses into the side of the controller. If the wire has 12 volts then the

screen needs to be replaced.
