Questions about this item

Will the PH-936-007 control board replace the board in my existing Dayton 1RKT4 furnace?

The PH-936-007 is listed as compatible with Dayton model numbers 1RKT4 and 1RKU2, matching the Grainger part numbers for those units.

How can I verify the PH-936-007 is operating correctly after installation?

After wiring, the board should initiate the ignition sequence and respond to thermostat calls for heat; a steady status light typically indicates normal operation.

Does the PH-936-007 package include wiring harnesses or a thermostat, or must I buy them separately?

The listing describes only the furnace control board itself; any required wiring harnesses or a compatible thermostat would be separate purchases.
