It sounds like your MaxxFan may need a new circuit board. Typically, when customers had similar issues they were able to replace the circuit board and their fan return back to normal operation. You can use Replacement Printed Circuit Board # MA10A21276K if you have MA00-04000K, MA00-05100K, or MA00-06200K. You can use Replacement Printed Circuit Board and Switch # MA10-04301k-v16 if you have MA00A04301K, 4201KW, 4251KW, or 4401KW. You will more than likely need the first option, # MA10A21276K. view full answer...
To reset the control panel of a Lippert Ground Control system unplug the control panel # LC421484 for several seconds and then plug it back in. We've seen just doing that alone fix most of the problems with the control panels. If that does not fix the error code let me know. view full answer...
