Control Board Summit Heat Pump SUM5
I have a 3 year old Hayward heat pump TA 50 that has the U4 chip fried, anything that I need to check before I replace the board? Thanks
Hi, Thomas. Check the transformer to make sure it puts out 24 vac to the board. If not, that along with the board will need to be replaced.
