This is an instructional guide detailing the cause for an overheated 120 Volt GFCI Head on a Plug & Play Spa (includes Portables and Acrylics).




The main cause for an overheating GFCI Head (aside from extension cord use) is a poor connection between the wires and the terminals.

This can be due to a loose terminal screw, a poorly inserted wire, insulation being inserted into the terminal, etc. 

A poor connection prevents the correct amount of contact which can cause the wires and terminal to heat up resulting in a melted plug and/or burnt wires inside the shell.

NOTE: Do not plug the GFCI into an extension cord. Your spa should be plugged directly into a dedicated household outlet to reduce chances of damage.

Please also ensure that the plug makes full contact with the outlet.

If water gets into the GFCI plug, it will cause it to trip. Be sure to protect the plug from rain/snow.
