That is a lowe water level error.

C27 is a Flex ROOM Damper Heater Error.

That code means there is a problem with a High temperature Heating error.

C24 indicates a Freezer Defrosting Error.

The “HE” error code indicates a heater error.

This error occurs when there is an issue with the fan motor. Either a bad wire or the motor itself.

The C22 is a refrigerator fan error.

Hello
See the link for your exact model number schematic wiring & parts breakdown. I also included a technician manual for the E30S075F series unit. We do not have your exact model technician sheet. Hope this helps.

Hello
See service manual link. Go to page #41 and walk through the flow chart diagnostics.

C21 is a Freezer Fan Error.

C15 is an Ice Room Sensor Error

The C14 is an Ice Maker (Fridge) Sensor Error.

c13 indicates an issue with your Humidity sensor.

Hello
See the service manual link below . You will find the complete diagnostics in the manual.

C7 error code indicates a problem with the Flex-Zone Temp sensor.

That error code is an issue with the External air sensor.

Hello
See technician manual link below. The #43 Error code is a cooling fan not operating . See page #20 in the manual link below for rectifying this code and the steps to troubleshoot.

Hello
See the service manual link below. Have you tried plugging the unit into a different outlet? You may have a weak breaker or fuse. If it not the outlet, you could have a defective magnetron or a few other possibilities. See magnetron testing below. If it tests fine go to page#10 in the manual link for other component testing.
Magnetron testing
1) Disconnect the power supply cord.
2). Open the drawer and keep it open
3. To discharge high voltage capacitor, wait for 60 seconds.
4. To test for an open filament, isolate the magnetron from the high voltage circuit. A continuity check across
the magnetron filament leads should indicate less than 1 ohm.
5. To test for a shorted magnetron, connect the ohmmeter leads between the magnetron filament leads
and chassis ground. This test should indicate an infinite resistance. If there is little or no resistance the
magnetron is grounded and must be replaced.
6. Reconnect all leads removed from components during testing.
7. Reassemble the unit.
8. Reconnect the power supply cord.
9. Run the oven and check all functions.
MICROWAVE OUTPUT POWER
The following test procedure should be carried out with the microwave oven in a fully assembled condition.
