cwbyjnky Posted February 21, 2011 Report Share Posted February 21, 2011 Hello We have had the tub since new, have not had any work done recently. When I disconnect the power from the tub the GFCI will not trip. When I disconnect the power to the heater the GFCI still trips. When I disconnect the 4 wires on the power bar for the heater the GFCI sill trips. When I disconnect the temp sensor the GFCI still trips. Any help would be appreciated. Also I have not used a multi meter before or have one, if I need one what size would you recommend to test. Quote Link to comment Share on other sites More sharing options...
n1oty Posted February 21, 2011 Report Share Posted February 21, 2011 If you keep testing that way, you'll cook the board, GFCI or both. Get a megohmmeter that goes to at least 20 megohms in order to ground fault test. I use a 40 megohm meter myself. You'll need to disconnect each load and properly ground fault test. Circ pumps and air blowers are common culprits on that particular tub, but be vigilant by also checking the jet pumps. John Hello We have had the tub since new, have not had any work done recently.
