GE Microwave SE Error Code: Temperature Sensor / Control Fault & How To Fix It
Quick Answer
Temperature Sensor / Control Fault: The oven or microwave detected an abnormal temperature reading or control board communication error.
Severity: High
When your GE Microwave displays the SE error code, the control board is reporting a Temperature Sensor / Control Fault condition. In plain terms: The oven or microwave detected an abnormal temperature reading or control board communication error. This guide explains what the code means on GE models commonly sold in Las Vegas, what usually triggers it, and when a licensed technician should take over.
Seeing SE on a GE Microwave can be stressful, especially if laundry or food storage is on the line. The Temperature Sensor / Control Fault fault is classified as high severity. Before you call for service, walk through the checks below — many GE owners in Southern Nevada resolve simple causes like clogged filters or supply issues without a service visit.
The SE code on your GE Microwave is not random — it is a diagnostic signal tied to Temperature Sensor / Control Fault. The oven or microwave detected an abnormal temperature reading or control board communication error. Because desert dust, hard water, and heavy daily use are common in Las Vegas homes, GE appliances here can develop issues faster than in milder climates.

What the SE Code Means on a GE Microwave
The SE error indicates Temperature Sensor / Control Fault. The oven or microwave detected an abnormal temperature reading or control board communication error. On most GE units, the display will hold the code until the fault clears or power is reset. If the code returns immediately after reset, an underlying component failure is likely.
Manufacturers design these codes so technicians can narrow diagnosis quickly. For homeowners, the key takeaway is whether the issue is user-correctable (filter, supply, door switch) or mechanical (pump, motor, sensor, control board).
Symptoms You May Notice
Before and during a SE (Temperature Sensor / Control Fault) fault on your GE Microwave, watch for these signs:
- Display shows SE continuously or flashes after cycle start
- Appliance stops mid-cycle and will not resume until reset
- Audible beeps or chimes accompany the fault code
- Related functions (drain, spin, heat, cool) fail while code is active
Symptoms can vary slightly by GE model year and control board revision. Always confirm against your owner's manual for model-specific behavior.
Common Causes
Based on field reports from Southern Nevada technicians, SE on GE Microwave units often traces back to:
- Failed oven temperature sensor (RTD) — Homeowners often overlook Failed oven temperature sensor (RTD) until SE displays; addressing this early can prevent costlier repairs on your GE Microwave.
- Faulty control board relay — In Clark County service calls, Faulty control board relay accounts for a significant share of SE diagnoses on GE Microwave appliances older than five years.
- Shorted heating element — On GE Microwave units in Las Vegas, "Shorted heating element" frequently appears before error SE when the control board detects abnormal operating conditions related to this component.
- Loose wiring at the sensor connector — Technicians report that Loose wiring at the sensor connector is a leading trigger for SE on GE Microwave models — especially after heavy use or following a power outage in the valley.
- Power surge damage — Homeowners often overlook Power surge damage until SE displays; addressing this early can prevent costlier repairs on your GE Microwave.
- Steam or grease intrusion into controls — In Clark County service calls, Steam or grease intrusion into controls accounts for a significant share of SE diagnoses on GE Microwave appliances older than five years.
Step-by-Step DIY Checks
Try these safe homeowner checks on your GE Microwave before calling a pro:
- Reset power at the breaker for 60 seconds — Homeowners often overlook Reset power at the breaker for 60 seconds until SE displays; addressing this early can prevent costlier repairs on your GE Microwave.
- Verify the cavity is cool before running self-clean — In Clark County service calls, Verify the cavity is cool before running self-clean accounts for a significant share of SE diagnoses on GE Microwave appliances older than five years.
- Inspect sensor bulb is not touching oven wall — On GE Microwave units in Las Vegas, "Inspect sensor bulb is not touching oven wall" frequently appears before error SE when the control board detects abnormal operating conditions related to this component.
- Cancel active self-clean if the code appeared mid-cycle — Technicians report that Cancel active self-clean if the code appeared mid-cycle is a leading trigger for SE on GE Microwave models — especially after heavy use or following a power outage in the valley.
- Check that clock is set after power outage — Homeowners often overlook Check that clock is set after power outage until SE displays; addressing this early can prevent costlier repairs on your GE Microwave.
What Not To Do
Do not attempt the following while troubleshooting this error:
- Do not run self-clean with active fault codes

When to Call a Technician
Gas ovens with F9 or lock-related codes need professional service. Call if the unit will not heat, overheats, or trips breakers. If you have completed basic checks and SE persists, schedule a licensed GE Microwave repair pro. Electrical faults, refrigerant issues, and gas-related errors should never be DIY.
Las Vegas Repair Considerations
Hard water mineral buildup, low-humidity dust infiltration, and year-round heavy use make GE Microwave error SE especially common in Clark County. If your unit is in a garage or laundry room without climate control, heat can accelerate sensor and seal failures.

Preventing SE From Returning
After repair, maintain your GE Microwave with regular filter cleaning, proper loading, and annual inspection of hoses and seals. In Las Vegas, wipe door gaskets monthly to prevent dust buildup that triggers sensor faults.
Use manufacturer-recommended detergent amounts and avoid overloading — both reduce strain on components linked to SE.
Long-Term Maintenance Tips
Schedule a professional tune-up every 12–18 months for your GE Microwave in desert climates. Technicians can catch worn hoses, weak pumps, and failing sensors before they trigger SE on the display.
Professional Diagnosis Process
A certified GE technician typically starts with a fault log readout, then tests components associated with Temperature Sensor / Control Fault. They verify power, grounds, and connections before recommending parts. This structured approach prevents unnecessary replacements and ensures the SE fault is fully cleared.
Ask for a written estimate before authorizing work. Reputable Las Vegas pros explain which test pointed to the failed part and what warranty covers the repair.
Recommended Troubleshooting Timeline
Use this order when addressing SE on your GE Microwave:
- Power cycle at the breaker for 60 seconds, then rerun the last cycle.
- Complete all DIY checks listed above — filters, hoses, seals, and supply valves.
- Document when the code appears (fill, wash, drain, spin, heat) for your technician.
- If the code returns twice after reset, stop using the appliance and schedule service.
- Request a written estimate before authorizing parts replacement.
Most Las Vegas homeowners resolve or isolate the issue within 30 minutes using these steps.
