I have a Raypak natural gas heater (model P-R336-A-EN-C, serial 050302). A few years ago the display broke from a tree falling on it. I replaced the switch membrane/pad and everything was good until water got to it (from the bent metal/tree). Last year I bought a MULAN 009491F Control Bezel with Switch Decal-Membrane, Compatible with Raypak Pool Heater from Amazon but didn't install it until this weekend. Everything works except for the LCD display. I cant see anything but the white light so I cannot adjust temperatures in the spa or pool, etc. Did I miss something that I was supposed to replace, or is there a contrast or backlight adjustment? Did I get the wrong part? I did notice the number of pins on the ribbon were different but I didn't think that would make a difference. Any help would be appreciated.
