Product Description
The Genie 30804A.S is a genuine OEM replacement step-down AC transformer designed for Genie GPS 1200, Genie GPS1200IC, Genie PMX1200 garage door openers. This transformer is a critical power supply component that converts standard 120 VAC household current to the lower AC voltage required by the opener's control circuit and drive motor. Using the correct model-specific transformer is essential - the GPS 700 and GPS 1200 transformers have different VA ratings and are not interchangeable. Replace only with the transformer designated for your specific opener model to avoid control board or motor damage. This part restores full power supply functionality when the original transformer fails due to overheating, electrical surge, or age-related degradation.

Frequently Asked Questions
Q: Is the 30804A.S the same as the 29058A.S used in the GPS 700?
A: No. The 30804A.S is designed specifically for the GPS 1200 and its higher-power motor. The GPS 700 uses transformer 29058A.S, which has a different VA rating. Installing the wrong transformer risks damage to the opener electronics.
Q: Why does the GPS 1200 need a different transformer than the GPS 700?
A: The GPS 1200 has a more powerful motor than the GPS 700, so it requires a transformer capable of delivering a higher VA output to maintain stable voltage under load. Using an under-rated transformer can cause voltage sag, erratic operation, or premature failure.
Q: Is this a genuine OEM part?
A: Yes. Part 30804A.S is a genuine OEM Genie replacement part, ensuring correct electrical specifications and physical fitment for the GPS 1200 and compatible models.
Q: What symptoms indicate a failed transformer in the GPS 1200?
A: Symptoms include a completely unresponsive opener, the control board resetting repeatedly under load, unusual heat from the power supply area, or a burning smell. Verify fuses are intact first, then test transformer output with a multimeter.
Q: Is installation of the 30804A.S straightforward for a DIY technician?
A: The 30804A.S is a direct drop-in replacement. Disconnect power, remove the old transformer, and connect the new unit using the existing wiring harness connectors. No modification is required.
