Common Symptoms of a Failing Lennox 59W47 M2 Unit Controller

The Lennox 59W47 (102630-01) M2 Unit Controller, commonly referred to as the Prodigy Control Board, is the primary control board used in many Lennox commercial rooftop HVAC units (RTUs). It manages heating, cooling, blower operation, safety circuits, and system communication. Whether your rooftop unit is servicing a building in Calgary, Edmonton, Red Deer, Lethbridge, Medicine Hat, or elsewhere in Alberta, or in the Greater Toronto Area, including Toronto, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Milton, Ajax, Pickering, and Oshawa, a failing controller may cause the following symptoms:

• Rooftop unit will not start.
• No heating or cooling despite a thermostat or building automation system call.
• Indoor supply fan fails to operate.
• Compressors fail to energize.
• Heating stages do not engage.
• Intermittent system operation or random shutdowns.
• Unit locks out on safety faults even after components have been verified.
• Loss of communication between system components.
• Diagnostic LEDs display fault codes or fail to illuminate.
• Burnt relays or visible damage on the control board from electrical surges.
