Frequently Asked Questions

How much does it cost to fix a garage door opener that's reversing mid-cycle?

The part costs about $20. If you do it yourself, that's your total cost. A professional service call would add $100-200 in labor, bringing the total to $170.

How long does this garage door opener repair take?

This repair is rated "easy" and typically takes 10-15 minutes. The most time-consuming part is usually accessing the component, not the actual swap.

What if this isn't the problem?

Our diagnosis is 85% likely based on the symptom you described. If replacing this part doesn't fix it, the next most common cause for "door starts to close then immediately reverses back up" would be related to the wiring harness or control board. In that case, consider calling a professional.

Should I just replace my garage door opener instead?

A new garage door opener costs $200-500. If yours is well under 10-15 years old, a $20 repair is far more cost-effective. If it's near end-of-life and has had multiple issues, replacement starts making more sense.
