SERIAL NUMBER 14-000001 AND UP

Burner shuts off for "Burner Power Break" or will not turn on

**Burner shuts off or always seeing "Burner Power Break " fault on screen.**

❏ During the purge cycle at the initial start up the burner ignitor box receives

all its power from the IQ controller. System is 120 volts and is used to

power the burner and fuel system.

❏ "Power Break" refers to the break in power to the burner. Test for loss of

voltage at the Ignitor box in the burner assembly. (See example "B")

❏ Terminal "N" & "L" are power in. If there is no voltage then check the IQ

controller for power loss. Power into the controller red terminal block

distributes voltage to the fan and burner.

❏ Check the red terminal block for power in and out (120 v). Make sure

connections are secure.

❏ Check the 15 amp fuse on the left of the controller. (Example "C"). If it

fails, replace it.

❏ Test for voltage into the power relay above the red terminal block. During

purge power goes to relay and out into the thermal breaker. (Example

"C"). If failed, replace it.
