Error 30/70 or 35/75 - AC input voltage out of range

What does 30/70, 35/75 mean?

These errors indicate that the AC input voltage supplied to the Induction Housing Assembly is either too high (30/70) or too low (35/75). The voltage should be within 240 Volts AC ± 10%.

• House voltage outside of acceptable range (should be 240VAC ± 10%)
• Faulty electrical jumpers on the Filter Circuit Board
• Defective Filter Circuit Board

Click steps to track your progress.

1. 1

   Measure the house voltage at the main incoming connections on the Filter Circuit Board (between terminals X1, X2 and X4, X5); the voltage should be 240 Volts AC ± 10%.

2. 2

   Inspect the electrical jumpers from X1 to X2 and X4 to X5 for damage or incorrect installation.

3. 3

   Ensure terminal X6, your chassis ground wire, is properly connected.

4. 4

   If proper voltage is present and connections are good, replace the Filter Circuit Board.
