| honeywell smart valve troubleshooting
I have a rooftop HVAC unit with a smart valve SV 9500 M.
I have replaced that flame sensor - pilot assy with no results. When t'stat calls for heat, inducer motor starts and the pilot then lights. The main burrner does not come on. Am I right thinking the valve is the problem. If any safety device is open, the pilot would not light, isn't that right. I hate to just replace parts. Thanks |
