Setup

- Prepare Jars: Ensure all glass jars are clean and dry before adding ingredients.
Operating Instructions
Basic Yogurt Making Process:
- Prepare Milk and Starter: Add your chosen yogurt starter (e.g., plain yogurt with live cultures or a yogurt starter powder) proportionally to the milk and mix well. Ensure the milk is at the appropriate temperature as per your recipe (typically around 100-115°F or 38-46°C).
- Fill Jars: Pour the milk and starter mixture into the individual glass jars.
- Place in Maker: Place the filled jars into the yogurt maker's main unit. You may add a small amount of warm water to the bottom of the main unit (around the jars) to help maintain uniform temperature during fermentation, though the PTC heating technology is designed for even heat distribution.
- Cover: Place the clear lid over the jars and the main unit.
- Set Time and Temperature: Plug in the appliance. Use the control panel to set your desired fermentation time and temperature. Refer to the 'Setting Time and Temperature' section below for detailed instructions.
- Start Fermentation: Press the 'Start' button to begin the fermentation process. The digital display will show the remaining time.
- Cool and Enjoy: Once the fermentation cycle is complete, remove the jars from the yogurt maker. Cover them with their individual lids and refrigerate for at least 4 hours to chill and firm up the yogurt before serving.

Setting Time and Temperature:
- Power On: Plug the yogurt maker into a power outlet. The display will light up.
- Set Time: Press the 'Function' button (or 'Time' button if available) to activate the time setting. Use the '+' and '-' buttons to adjust the hours (0-99H) and minutes (0-59M).
- Set Temperature: After setting the time, press the 'Temp' button. Use the '+' and '-' buttons to adjust the temperature (77℉ to 149℉).
- Start: Once both time and temperature are set, press the 'Start/Cancel' button to begin fermentation. The display will show the countdown.
The yogurt maker has a memory function that remembers your previous settings, making it convenient for repeated use.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Yogurt is too thin/not setting | Incorrect temperature or fermentation time; insufficient starter culture; milk not heated/cooled properly. | Ensure correct temperature (typically 100-115°F) and time (6-12 hours, or longer for thicker yogurt). Use fresh starter with live active cultures. Heat milk to 180°F then cool to desired fermentation temperature before adding starter. |
| Yogurt is too sour | Fermented for too long or at too high a temperature. | Reduce fermentation time or temperature in future batches. |
| Yogurt has a grainy texture | Milk was heated too quickly or not stirred enough during heating. | Heat milk slowly and stir constantly to prevent scorching. |
| Appliance does not turn on | Not properly plugged in; power outage. | Check power connection. Note that the unit may not resume operation after a temporary power outage; settings may need to be re-entered. |
| Temperature is inconsistent | Lack of water bath (if using individual jars). | For optimal temperature stability, add warm water to the main unit around the jars, ensuring it does not overflow into the jars. |
