A flashing F code may indicate damage to the heating coils, commonly caused by pressure applied to the pad which can cause a connection error. The blinking F may indicate a connection error caused by damage in the coils. To ensure safe and effective use, we recommend avoiding pulling or bending the pad connector, as well as refraining from folding or bending the pad while it is still hot. These precautions help to keep you safe and protect the pad from potential damage.
Please try using the troubleshooting steps below, which may help:
1. Unplug the unit
2. Disconnect the control connector from the pad connector
3. Reconnect the cord and pad connectors
4. Control connector must be connected to the Pad Connector before plugging the unit into an electrical outlet.
