Product Description
The Genie GE-29058A.S is a genuine OEM replacement step-down AC transformer designed for Genie GPS 700, Genie GPS700IC, Genie GPS1200IC, Genie PMX700, 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: Can I use the 29058A.S transformer in a GPS 1200 opener?
A: No. Part 29058A.S is rated and designated for the GPS 700 opener. The GPS 1200 uses transformer 30804A.S, which is a different VA rating to match its higher-power motor. Using the wrong transformer can damage the control board or motor.
Q: What does this transformer do inside the GPS 700 opener?
A: The transformer steps household AC voltage down to the lower AC voltage required by the GPS 700 power supply circuit. That lower AC voltage then feeds the rectifier or control board to power the DC drive motor and logic electronics.
Q: Is this an OEM part?
A: Yes. Part 29058A.S is a genuine OEM Genie replacement part, ensuring correct voltage, VA rating, and physical fit for the GPS 700 and compatible Stealth-series models.
Q: How do I know if my GPS 700 transformer needs replacement?
A: Check for the original transformer showing signs of overheating, burning smell, no output voltage when measured with a multimeter, or a blown fuse upstream. If the opener is completely dead after verifying fuse and rectifier are good, the transformer is a likely suspect.
Q: Do I need an adapter or wiring harness to install this transformer?
A: No adapter is required. The 29058A.S is a direct plug-in OEM replacement designed to fit the GPS 700, GPS700IC, and compatible PMX-series enclosures without modification.
