# Why won't my compressor start?

## What to do if your Display Panel is on, but your compressor does not start

1. **Set** mode to **Cooling (Snowflake icon)** : Press the mode button and make sure the snowflake icon is on.
2. Remove/access the back of the **Display Panel** and check that all connections are secure.
3. Remove the top cover to verify that the screw/bolt connections to the **compressor controller** and compressor are tight. Also, check that the **white connectors** on the **compressor controller** are connected tightly.
4. Make sure the **ambient temperature** is 67 F or above, and that the **set temperature** is set about 10 degrees below the **ambient temperature**. Wait for the unit to run for 10 minutes. Sometimes the compressor has a delayed start to equalize inside pressure as well as prevent **short-cycling.**

**If the issue persists, call Support to replace the display panel**
