IPB-16S GFCI doesn't want to work

I have an IPB-16S that to use with my brewing setup.

I have tried it in numerous outlets (all verified to be good with appropriate tools) including GFCI and non-GFCI. Almost all cases the unit will not enable when plugged in - reset won’t turn it on. I have gotten it to turn on once when plugged into kitchen GFCI (where I do brewing) and it lasted for about five minutes.

Given this is on multiple outlets, and even without anything plugged into the controller, I feel the GFCI is probably dead.

Hello,
May I know is this your first time using it?
Could you please let me know the voltage of the power supply you are using?
What is the wattage of the heater and pump?

This is the first time.

120V mains
1650W heater (13.75A)
12W pump (0.1A)

Please note: this happened without anything plugged into it and the unit off.

Thanks!

I have this problem as well. Even when the unit is powered off, the GFCI is tripped.

Hello,
Do you mean that even if the IPB-16S is switched off, it will cause a trip?
Is the IPB-16S body kept in a cool, dry environment? Will it also trip if the heater is not plugged in?
If yes, please email support@inkbird.com with order information and a video of this problem.
