The Goodman 0130M00138S Transformer is a genuine OEM step-down control transformer that supplies the 24-volt control circuit in CPC036XXX1DXXXBA air conditioning systems. It powers the thermostat, relays, and contactor coil. A blown transformer leaves the system completely unresponsive — no thermostat display, no cooling call, no contactor pull-in — often caused by a control short or power surge.

OEM vs. Generic

The OEM 0130M00138S delivers the exact 40 VA rating and primary tap configuration your unit expects, ensuring stable control voltage. Undersized generic transformers can overheat under load and fail again, while mismatched primary voltages risk damage. OEM is the safest long-term choice.

Installation Difficulty

Easy to moderate — about 20–30 minutes. Disconnect power, label the primary and secondary leads, mount the new transformer, and reconnect. Before powering up, verify line voltage feeding the primary and check for the original control short that may have caused the failure.

My thermostat has no power. What failed?
