Product Overview
The RVCTBD50 is a rev counter board used inside select Mighty Mule, GTO, and Linear PRO gate opener arm assemblies. Its job is to provide feedback from the motor/gear system so the control board can understand arm movement and manage gate travel.
When a rev counter board fails, the opener may run briefly and stop, beep a diagnostic code, lose its learned limits, or act like it cannot properly count gate movement. These symptoms can also be caused by wiring, battery, control board, or mechanical binding, so the board should be diagnosed before replacement.
This part is commonly used across several older Mighty Mule and GTO/Linear PRO arm families, but it is not universal. The original arm model and the board style should be checked before ordering, especially on operators that have been repaired before or converted between single and dual gate setups.

Technician Note
A rev counter fault can be caused by the board, but also by broken wires in the arm harness, a weak battery, a dragging gate, or a failing control board. Diagnose before replacing multiple parts.
Before Ordering
- Confirm the original board number is RVCTBD50.
- Match the opener arm model and generation.
- Inspect the arm wiring harness for cuts, corrosion, or loose plugs.
- Check the gate for binding before blaming the electronics.
- Review any beep or diagnostic pattern from the control board.
Professional Advisory
Do not bypass feedback or safety circuits to keep a gate running. If the operator moves unpredictably or will not stop correctly, disconnect power and have the system inspected.
Product Questions and Answers
What does the RVCTBD50 board do?
It helps the operator count motor revolutions so the control system can track arm movement and gate travel.
What symptoms can point to a bad rev counter board?
Stopping after a short run, repeated beeping, lost travel count, or failure to complete a cycle can point to a rev counter issue, but other faults can cause similar symptoms.
Which models commonly use RVCTBD50?
It is commonly listed for Mighty Mule 2500, 2502, 2550, MM350, MM352, MM360, MM500, MM502, MM560, MM562, MM600, and MM660 series applications.
Is RVCTBD50 a main control board?
No. It is a feedback board used in select opener arms. The main control board is a different part.
Should I replace this board if the gate is hard to move by hand?
No. A dragging or binding gate should be corrected first because mechanical load can create electronic fault symptoms.
