Arrived at location on 6/17/22 - Found error f3 magnitron current error. Check found magnetrons slow to ramp up to full amp draw. Found magnetrons clogged with dirt and overheated found capicators weak and diodes were bad. I did replace the mags diode capicators and cleaned up the cooling fan and main fan motor area and cook chamber. I checked operation. Magnetrons now ramping up, correctly. I did erase the error logged. Unit is working as it should and ready to use.
