How to Take an Amp Draw
If any component from the microwave circuit fails or the food is not cooking properly, the first thing
that should be done is take an amp draw on the CT wire. The target amp draw on both circuits for a
208V unit is between 14-15 amps, a unit supplied with 240V will be between 13-14 amps. Each
microwave circuit can be isolated by removing both primary wires to the HV transformer. Never
attempt to isolate by removing the secondary wires due to high voltage.
1) Remove both the right side panel of the unit.
2) Locate the CT that is connected around the wire number 36 of the power distribution bar.
3) Inside the Option Screens, click on the icon “Settings” and insert the password from
manufacturer: 459381.
4) Go to menu “Electrical Loads Test”.
5) Place your amp clamp on one side of the brown wire.
6) Press the icon “Microwaves Test” to start the magnetron test. This function will engage both
microwave circuits and give a combined amp draw.
