Do I Have a bad Topside Control or Main Board Problem?
I have a 00 sweetwater Palmero. I recently hooked it up and had a FL1 code. Replaced the pressure switch and code cleared. Lights (topside Control) come on but nothing happened.I turned it off for a night & turned it back on. The topside control was flickering a bunch of random things (ON8, ON3, Etc.) Then the topside control went blank but the system turned on. The topside control had no digital display or indicator lights while running unless you pressed the temp up/down, Light or Pump keys. The system ran for about 12 hours overnight and heated up to 87 Degrees. When I checked it in the morning the system was not running but the topside control was working properly (Reading 87, No Flickering). I turned the power off, unplugged the topside control, plugged it back in & turned power back on. The topside control lights up reads 87 but the system will not turn on.
