It steps line voltage down to the 24V control power required by the thermostat, contactor coil, and defrost board. A weak or failed transformer is one of the most common causes of a completely dead control circuit — no thermostat display, no cooling, no heat.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 0130M00138S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRating:\u003c\/strong\u003e 40VA control transformer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary:\u003c\/strong\u003e 208\/240V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary:\u003c\/strong\u003e 24V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Goodman\/Amana heat pumps incl.
