Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Warmer does not turn on. | Not plugged in; Power outlet issue; Unit malfunction. | Ensure power cord is securely plugged into a working outlet. Try a different outlet. If problem persists, contact customer support. |
| Temperature is not reaching the set point. | Incorrect temperature setting; Environmental factors (cold room); Jar too large/thick. | Verify the temperature setting. Ensure the room temperature is not excessively cold. The warmer is designed for jars up to 40oz; very thick glass or larger jars may affect performance. |
| Display is not working correctly. | Temporary glitch; Unit malfunction. | Unplug the unit for 1 minute, then plug it back in. If the issue continues, contact customer support. |
| Red light stays on, blue light never illuminates. | Warmer is continuously heating to reach set temperature. | This is normal if the set temperature is significantly higher than the ambient temperature or if the jar is very cold. Allow more time for the temperature to stabilize. |
