genie opener buy new end of story. Transformers burn up usually from another issue. You can find a transformer, put it in and burn it up also. Piff, it could have been nothing more then a simple power surge. Transformers are the first thing to go in HVAC if you get a surge. |

Before you replace the transformer, check the capacitors for a short. Previous comment about something else taking out the transformer probably true. Common
cause of that is shorted capacitor. |

Sequencer board on the opener is dead. It has a short on the 5VDC power supply chip output to ground. It's internal to the board and I cant trace it down. Ohh, well. I tried.
Good news is I found a Craftsman opener on craigslist for $25. Brand new house and homebuilder used a chain drive opener. It was switched out to a Chamberlain whisper drive one since it was right below the bedroom. Picking that up between today and Saturday. |
