there is a 100uf/63v capacitor near the IRF630 fet. You need to replace this in order to fix this error. Along there is also a 2200uf/16v capacitor. It is a good idea to change the both at the same time.

This error can only be cleared by the Eaton technician with their laptops. If this is a new unit it HAS to be factory started or your warranty will be void.

Honestly, the cost of repair might exceed the cost of a new unit. We can likely get any parts needed to repair the unit, but might not be the most cost effective solution. Might want to price around for a replacement unit. If you need additional assitance, please contact us.
