E1 Error (Outdoor Unit); Relevant Test Points On The Main Outdoor Pcb - Electrolux KELVINATOR KSV53HRA Diagnostic Manual

E1 error (Outdoor Unit)

If E1 fault has not cleared:
Check the continuity of the "Bridge Rectifier" as illustrated below.
Turn off the power & let the inverter electrolytic capacitors completely discharge.
Identify the diodes individual 'Plus' and 'Minus' connections so as to test each diode's forward and
reverse resistance values. The diagrams listed below illustrate the method of achieving this.
Set the multimeter to a DC Mega Ohms setting.
Place the Positive probe on the
Place the Positive probe on the O pin of the rectifier & the Negative probe on the

Note: Insure the multimeter probes are placed in their correct orientation as specified above.
Note: If any of the above tests indicate a "Short Circuit" replace the main PCB assembly.
All of the above tests should read several Mega Ohms.
