If your Sharp microwave is displaying an error code, this means you have a clue to resolve the problem. Find the code in the tables below to learn what you can do. In case of a significant issue, the manufacturer recommends that you call for service or call an electrician.
| Fault code | Definition |
|---|---|
| F1 | Open Thermal Sensor, due to excessive heat in microwave cavity |
| F2 | Shorted thermal sensor |
| F3 | Shorted touch pad panel |
| F4 | Open humidity sensor |
| F5 | Shorted humidity sensor |
| F6 | Shorted temperature probe |
| F10 | Shorted touch screen |
| Probe | Open temperature probe or the probe is not plugged in during a temp cook function. Make sure probe is firmly inserted into the wall of microwave and the food item. |
| 888, 8888 or PF | It is possible to see this display upon initial installation or after power was restored due to a power failure. This display can be cancelled and normal operation resumed by touching the CLEAR pad. The clock can be reset on models so equipped. |
| 18 power watch code | Indication of an issue with the electronic control in the microwave. |
| DISPLAY | CONDITION | POSSIBLE CAUSE (In order of probability) |
|---|---|---|
| F33 | Open temperature sensor (exhaust) | 1. Loose ground screw on the digital programmer circuit |
| 2. Loose connector CN4 | ||

| No Display (Dead) | No voltage supply to the LV transfomer | 1. Right fuse open |
| 2. Damaged short switch | ||
| 3. Shorted H.V capacitor, transformer, diode or magnetron (upper) | ||
| 4. Shorted L.V transformer (Relay board) | ||
| 5. Digital programmer circuit failure | ||
| F81 | Excessive current comsumption (upper H.V circuit) | 1. Open primary latch sw itch |
| 2. Relay failure RY-3 (Relay Board) | ||
| 3. Digital programmer circuit failure | ||
| F82 | Excessive current comsumption (lower H.V. circuit) | 1. Left fuse open |
| 2. Open primary latch switch | ||
| 3. Damaged short switch | ||
| 4. Shorted H.V capacitor, transformer, diode or magnetron (lower) | ||
| 5. Relay failure RY-4 (Relay Board) | ||
| 6. Digital programmer circuit failure | ||
| F86 | Shorted contacts of RY-3 | 1. Relay failure RY-3 (Relay Board) |
| 2. Digital programmer circuit failure | ||
| F87 | Shorted contacts of RY-4 | 1. Relay failure RY-4 (Relay Board) |
| 2. Digital programmer circuit failure |
| EE Mode | Reason | Action Required |
|---|---|---|
| EE 1, EE 2 | Failure of single magnetron | Call for service. |
| EE 3 | Both magnetrons failed | |
| EE 4 | Voltage too high | |
| EE 5 | Voltage too low | |
| EE 7 | Oven cavity or component temperature too high | Check that nothing is blocking air intake openings on oven back or that oven exterior is very hot. Correct. Wait a few minutes and try again. If problem persists, call for service. |
| EE 8 | Circuit failure | Call for service. |
| EE 9 | Maximum cooking time is exceeded. | Press the STOP/CLEAR pad, and re-input by reducing Total Cooking Time or power levels. |
| EE 0 | Cooling fan motor and other motor failure. Oven ceiling cover is not installed properly. | Cooling fan motor and other motors: Call for service. |
| Oven ceiling cover: Check that oven ceiling cover is properly installed. If problem persists, call for service. |
| EE Mode | Reason | Action Required |
|---|---|---|
| EE 1, EE 2 | Magnetron failure | Call for service |
| EE 3 | Both magnetrons failed | |
| EE 4 R-23GT, R-24GT and R-25JT only | Voltage too high | If problem is not corrected, call an electrician. |
| EE 5 R-23GT, R-24GT and R-25JT only | Voltage too low | If problem is not corrected, call an electrician. |
| EE 6, EE10, EE16 | Thermistors failure | Call for service. |
| EE 7 | Exhaust air temperature too high | Check that nothing is blocking air intake openings on oven back or that oven exterior is very hot. Correct. Wait a few minutes and try again. If problem persists, call for service. |
| EE 8 | Circuit failure | Call for service. |
| EE 9 | Maximum time is exceeded | Touch STOP/CLEAR pad, and reprogram correctly. |
| EE 0 | Fan lock error | Call for service. |
| EE17 | Magnetron temperature too high | Touch STOP/CLEAR pad. Wait a few minutes and try again. If problem persists, call for service. |
