Common Problems & Solutions

Problem: No Heating / Warming Mat Not Heating

The warming mat is powered on but does not heat up, or food stays cold.

Possible Causes & Solutions:

  • Cause 1:

    Solution: Unplug the device, check that the control panel connector is firmly inserted into the heating pad port. Reconnect securely and plug back in.

  • Cause 2:

    Power cord not fully plugged into outlet

    Solution: Check that the power plug is completely inserted into a working 110V outlet. Test the outlet with another device if necessary.

  • Cause 3:

    Temperature set too low or device in standby mode

    Solution: Press the power button to activate heating mode. Adjust temperature higher using the temperature control knob.

  • Cause 4:

    Child lock activated preventing operation

    Solution: Press and hold the lock button for 1.5 seconds to deactivate child safety lock.

The temperature or timer display is not illuminated or showing readings.

Possible Causes & Solutions:

  • Cause 1:

    Device not powered on or in standby mode

    Solution: Press the power button to activate the warming mat. The display should light up with temperature reading.

  • Cause 2:

    Poor connection between control panel and heating pad

    Solution: Unplug device, disconnect and reconnect the control panel to the heating pad firmly, then plug back in.

  • Cause 3:

    No power supply to device

    Solution: Verify outlet is working, check power cord connections, and ensure plug is fully inserted.

    Control panel malfunction or damage

    Solution: Contact customer support at 13410039885@163.com for repair or replacement options.

Problem: All Display Lights Flashing

All indicator lights on the control panel are blinking or flashing continuously.

Possible Causes & Solutions:

    Temperature sensor malfunction or connection issue

    Solution: Turn off and unplug the device. Wait 30 seconds, then reconnect control panel firmly to heating pad. Plug in and restart.

  • Cause 2:

    Overheating protection triggered

    Solution: Unplug immediately and allow the warming mat to cool for at least 30 minutes. Check for obstructions on heating surface. Ensure proper ventilation.

    Control panel electronic malfunction

    Solution: Try a complete power reset: unplug for 5 minutes, then reconnect. If problem persists, contact customer support for repair.

  • Cause 5:

    Physical damage to button mechanism

    Solution: Inspect for cracks or broken buttons. Do not attempt self-repair. Contact manufacturer for authorized replacement control panel.

Problem: Uneven Heating or Cold Spots

Some areas of the warming mat are hotter or cooler than others.

Possible Causes & Solutions:

  • Cause 1:

    Dishes not evenly distributed or too large

    Solution: Position dishes evenly across the heating area. Ensure dishes are within the designated heating zone for optimal heat distribution.

  • Cause 2:

    Debris or water on heating surface blocking heat transfer

    Solution: Clean the heating surface thoroughly. Remove rice grains, crumbs, or liquid before placing dishes.

  • Cause 3:

    Warming mat on uneven or heat-absorbing surface

    Solution: Place warming mat on a flat, stable, heat-resistant surface. Avoid metal countertops or surfaces that absorb heat.

  • Cause 4:

    Heating element damage or degradation

    Solution: If heating remains uneven after cleaning and proper placement, the heating element may be damaged. Contact customer support for inspection.

Problem: Odor or Smell From New Warming Mat

New warming mat emits a slight plastic or chemical smell during initial uses.

This is Normal:

A slight odor when first using your food warming mat is completely normal and expected. This is due to:

  • • New silicone and electronic components heating for the first time
  • • Manufacturing residues burning off during initial heating cycles

Solution: Run the warming mat for 15-20 minutes at medium temperature without food in a well-ventilated area. The odor should dissipate after the first few uses. If smell persists beyond 5 uses or becomes stronger, contact customer support.

When to Contact Customer Support

If you experience any of the following, discontinue use immediately and contact customer support:

  • Physical damage: Cracks in heating pad, broken control panel, or exposed wiring
  • Electrical issues: Sparking, burning smell (not normal new-product odor), or electric shock
  • Persistent malfunctions: Problems that don't resolve after troubleshooting steps
  • Overheating issues: Excessive heat, melting, or surface deformation
