Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | Main ON/OFF switch on the back is off, or battery is depleted/incorrectly installed. | Ensure the main ON/OFF switch on the back is in the "ON" position. Check battery installation and replace if necessary. |
| Temperature alarm does not sound. | TEMP ALERT switch is off, or target temperature not set. | Slide the TEMP ALERT switch on the front to "ON". Verify that a target temperature has been set. |
| Timer alarm sounds only once and then counts up silently. | This is the intended behavior for this model. | Be attentive to the initial alarm. The unit will continue to display the elapsed time after the alarm stops. |
| Inaccurate temperature readings. | Probe not fully inserted, or probe damage. | Ensure the probe is fully inserted into the food. If readings remain inaccurate, the probe may need replacement. |
