Frigidaire Microwave Error Code E-11: Gas Sensor Fault... | appliancefaults.com

Technical Background:

The E-11 error code indicates a fault in the gas sensor circuit. The Main Control Unit (MCU) monitors the gas sensor's voltage output. If the voltage is outside the acceptable range, the MCU triggers the E-11 error. The sensor operates on a 5V DC circuit derived from the main control board.

Symptoms:

The Frigidaire microwave displays an E-11 error code. The microwave may not operate or may shut down unexpectedly. There might be a faint odor detected near the microwave.

Possible Causes:

Faulty gas sensor
Loose or corroded wiring connections
Damaged wiring harness
Control board failure
Gas leak affecting sensor readings

Solution:

1

Disconnect the microwave from the 120V AC power outlet.
2

Locate the gas sensor. Refer to the service manual for its specific location within the microwave.
3

Visually inspect the sensor and its wiring for any signs of damage, corrosion, or loose connections.
4

Use a multimeter to check the sensor's resistance. Compare the reading to the value specified in the service manual.
5

Inspect the wiring harness connecting the sensor to the control board. Check for continuity using a multimeter.
6

If the sensor and wiring are good, suspect a faulty control board. Replacement may be necessary.
7

After repairs, verify proper ventilation and check for gas leaks before reconnecting to power.

Safety Warning:

Always disconnect the microwave from the power supply before performing any repairs. Use appropriate Lock-Out/Tag-Out (LOTO) procedures to prevent accidental energizing. Be aware of high voltage components within the microwave.

Prevention:

Regularly clean the microwave interior to prevent food debris buildup that could affect the sensor. Ensure proper ventilation around the microwave to prevent gas accumulation.

Expert Tip:

Some Frigidaire microwave models have a diagnostic mode that can provide more detailed information about the E-11 error. Consult the service manual for the specific key sequence to enter diagnostic mode. Often pressing the STOP/CLEAR button then entering a specific sequence of numbers will activate the service mode.

Frequently Asked Questions

•What is the typical resistance range for a functional gas sensor in this microwave model?

The typical resistance range for a functional gas sensor is between 1k ohms and 5k ohms at room temperature. However, refer to the specific service manual for the exact range for your model.

•Where can I find the service manual for my specific Frigidaire microwave model?

You can usually find the service manual online by searching for "Frigidaire microwave service manual" followed by your specific model number. Websites like AppliancePartsPros or RepairClinic often have them available. You can also check the Frigidaire website.

•If the gas sensor is reading within the correct resistance range, what is the next most likely cause of the E-11 error?

If the gas sensor's resistance is within the specified range, the next most likely cause is a faulty control board. Double-check the wiring harness continuity, but if that's also good, replacing the control board is the probable solution.
