Rheem Furnace: Replacing the furnace control: keep the memory card and copy the dipswitches
Replacing the furnace control: keep the memory card and copy the dipswitches on a Rheem furnace: The model data lives on a memory card tethered to the furnace; the new control is useless without it.
Applies to: (-)96VA040-115 (R96V / U96V) and (-)(-)96MDV040-115 two-stage variable-speed communicating furnaces
How to fix replacing the furnace control: keep the memory card and copy the dipswitches: step by step
- Pull the memory card out of the old control and plug it into P6 of the replacement. Do not cut the plastic tether.
- Copy every dipswitch position from the old board to the new one.
- Never use a control or card from another furnace, condenser or air handler. A lost card is ordered from ProStock by furnace model and serial number; cycle power after fitting it or the data is not read.
