Eufy Grill 3305 Not Heating? Try This First [2026]

Quick Fix Summary

Most Eufy electric grill Model 3305 heating issues come down to power delivery, a tripped safety interlock, or a dirty temperature sensor. Before anything else, seat the grill plate and drip tray fully, plug the grill into a dedicated outlet, and perform a soft reset by unplugging for 60 seconds. A quick clean of the plate-to-base contacts and the temperature sensor often restores normal preheat and accurate temperature control.

Step-by-Step Troubleshooting

Use the steps below in order. Always unplug the grill and allow it to cool completely before opening panels or touching internal parts. The Model 3305 typically draws about 1500 W at 120 V (roughly 12.5 A), so it should be used on a dedicated 15 A kitchen circuit without extension cords or power strips.

Before you begin

• Tools: microfiber cloth, mild degreaser, small brush, IR thermometer or probe thermometer, multimeter (optional), #2 Phillips screwdriver (only if out of warranty and comfortable with basic checks).
• Safety: unplug, cool fully, and never bypass thermal safety devices.

1. Confirm outlet and power path. Plug a lamp or phone charger into the same outlet to verify it is live. If the outlet is GFCI, press Reset. Avoid extension cords; if you must use one temporarily for testing, use a heavy gauge 14 AWG or better. A 1500 W grill on a weak or shared circuit can underheat or cycle off prematurely.
2. Inspect the power cord and plug. Look for cuts, kinks, or heat discoloration on the cord and blade tips on the plug. Wiggle the plug gently in the outlet while the unit is off to check for play. If you have a multimeter, unplug the grill and test continuity from the plug to the base where the cord enters; any open circuit or intermittent reading indicates a bad cord that must be replaced.
3. Soft reset the control and set a proper test. Unplug the grill for 60 seconds to clear latched faults. Plug back in, set the temperature to High (or 450 F / 232 C if a numeric setting is available), and start preheat with the lid closed. Preheat should take about 7 to 10 minutes, and the indicator should cycle once the target is reached.
4. Seat the grill plate, drip tray, and check interlocks. Remove the grill plate and drip tray, wipe away grease, and reinstall them firmly until fully seated. Many countertop grills rely on plate seating and lid position to close a safety microswitch. Open and close the lid and listen for a faint click near the hinge. If the lid switch does not click or is sticky with grease, clean the hinge area and try again.
5. Clean the temperature sensor and electrical contacts. The Model 3305 typically uses an NTC sensor near the center of the plate. Grease or carbon on the sensor or plate-to-base contacts can fool the controller into early shutoff. With the unit cool and unplugged, remove the plate and gently clean the exposed sensor nub and contact pads using a cloth dampened with mild degreaser. Dry everything thoroughly before reassembly.
6. Measure actual surface temperature. Use an IR thermometer to check the center of the cooking surface after 8 to 10 minutes on High. You should see 400 to 500 F at the hottest zone. If the indicator says it is hot but the surface stays below 300 F, suspect a weak connection, an open element segment, or sensor error.
7. Check the heating element continuity. Only if you are comfortable and the unit is out of warranty: unplug, cool, and carefully remove the bottom screws to view the element terminals and wiring. Disconnect the element from the controller and measure resistance across the element leads. For a 1500 W element at 120 V, expect roughly 9 to 12 ohms (V^2 / P = 14400 / 1500 = 9.6 ohms). Infinite resistance means a blown element; near zero means a short. Either condition requires replacing the element assembly.
8. Test the temperature sensor (NTC) and wiring. With the grill unplugged and cool, locate the two small wires from the sensor to the control board. An NTC sensor typically measures tens to hundreds of kilo-ohms at room temperature and decreases as it warms. An open (OL) or 0 ohm reading indicates a failed sensor or broken harness. If you cannot access the sensor, note symptoms: instant overheat warnings, wild temperature swings, or never leaving preheat often point to a sensor fault or loose connector.
9. Examine thermal fuse and high limit safety. Many grills include a non-resettable thermal fuse in a white fabric sleeve near the element. Test continuity end-to-end. If it is open, it tripped from excessive heat. Replace it with the same temperature rating only; do not bypass. Also correct the root cause: blocked vents, heavy grease buildup, or running without the plate fully seated.
10. Resolve GFCI trips, smoke, or odor. If the GFCI trips immediately, moisture may be in the base. Remove the plate and drip tray, wipe all surfaces, and allow the unit to air dry 24 hours. For heavy smoke on first use or after a spill, deep clean the plate, drip tray, and the element cavity (do not immerse the base). A thin coat of high smoke point oil and proper preheat will reduce sticking and smoke.
11. Fix uneven heating or hot spots. Verify the plate sits flat and locked. Check for burned-on residue insulating one area; scrub clean. If only one side heats, the element may be partially open or a spade connector loose. Reseat connectors firmly; if damage or pitting is visible, replace the element assembly and the affected connector.
12. Know when to contact support. If the unit is under warranty, stop disassembly and contact Eufy support with the serial number, proof of purchase, and a short video showing the issue and indicator lights. For out-of-warranty units with multiple failed components (element plus control board), replacement may be more cost effective than repair.

Technical notes and specs

• Power: approx. 1500 W at 120 V (12.5 A). Use a dedicated 15 A circuit.
• Expected element resistance: around 9.6 ohms at room temperature.
• Preheat: 7 to 10 minutes to reach searing temperatures with lid closed.
• Common sensors: NTC thermistor; resistance decreases as temperature increases.

Replacement Parts

If a component tests faulty, replacing the part often restores full performance. Match parts to Eufy electric grill Model 3305 and verify voltage and connector style. Use only OEM or quality equivalents, and never bypass safety devices.
