I have been trouble-shooting my gunite spa blower motor and I have narrowed the problem down to either the spa side air button, (best guess an Allied Innovations AIR BUTTON: #4 LITE TOUCH Black FOR GUNITE), or the air tube run from the spa to the switch. My question, has anyone removed one of these gunite mounted buttons? I am guessing that it will pry, not screw, out. I am worried that I will ruin the button or disconnect from the air hose when removing. Any experienced coaching is greatly appreciated!
