2cnd time this has happened.evap.motor wouldn`t run,replaced motherboard.evap.motor came back on. 1 day later damper stuck closed,just replaced damper thermister,to early to tell if this worked,will post later.any thoughts?
Rip, couple of checks to do: On the main board, connector J3. On the harness you should have 400 ohms on J3-1 (yellow) to J3-2 (red/black) and 400 ohms on J3-3 (white/brown) to J3-4 (blue yellow. Same values should be at the damper motor. If you don't have those values, damper motor defective. One other check, you have 10 seconds to do this on power up, so get some help. Plug in the refer. Check for 6 VDC. DC voltage now from pins J3-1 to J3-4. If you don't have this it's the board. If you do have this and the dampers not working, replace the damper. Catriver.
