Frequently Asked Questions
Q: How do I know if my control board has failed?
A: Common signs include the thermostat not responding to temperature adjustments, the AC compressor not engaging, error codes on the display, or the fan running continuously. If your AC worked before and suddenly stopped responding to controls, the board is often the issue.
Q: Will this board work with my 3310A or 3315A unit?
A: Yes, this board is designed for the 3310 and 3315 series, including A-model variants. Always verify your exact model number on the AC unit itself before ordering to ensure compatibility.
Q: Is this a difficult installation?
A: The board mounts inside your rooftop AC unit and connects via a harness. Most RV owners can handle this with basic tools, but if you're uncomfortable working on rooftop equipment, a qualified RV technician can install it in under an hour.
