Customer Question

my heater is not heating. temp dropped to 32 degrees. blowers and pump is still working. Can dirty filter stop heater from working? or what should I look for. There is a yellow/green wire that comes out of the heater- -seems to be connected beside the ground wire- - its not connected to anything. Please help.
JA: I'll do all I can to help. Is there anything else the Pool Technician should be aware of?

My name is Billy.

The number one fault is the flow switch not closing. This can be from dirty filters, obstruction, pump issue or a bad switch itself.

Remove the filters and see if the unit runs without the filters. If it does you will need to clean/replace the filters. If will reguire an electrical meter to see if the flow switch is closing.
