## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy swap-out. Nice job Protech!
*by N***K on May 26, 2018*

It seems like the photo got changed for this review showing three capacitors. Beats me why that happened, but this review is for the control board that takes the place of Rheem P/N 47-21517-22. Even though this Protech board looks different, it is an exact replacement. The installation was straight forward. My old board had hard wired temperature sensors. The new board has plug-in sensors. Don't worry they have "idiot-proofed" the connections by using different width connectors. My old board screw mounted to the inside of the box. The new board kit includes an adapter plate that allows you to use the new board that snaps in. Holes match right up - couldn't have been easier. Don't fear the P/N change! This is a direct replacement. Protech did a great job.

### ⭐⭐⭐⭐⭐ Easy to install, works great, I'm cool!
*by C***L on September 14, 2022*

The first unit was defective but it was replaced quickly and picked up by the carrier. The new unit works perfectly, I'm happy and cool! Good value backed up by the seller.

### ⭐⭐⭐⭐⭐ Works great
*by L***E on August 14, 2023*

Perfect match for part number 47-21517-22. Came with everything needed to replace the broken circuit board on my Rheem.
