this is my first post here being new and all...
I have a raypak pool heater, milivolt system, model pr265b-mn, it is natural gas 265000btu.
last year i repalced the pressure switch, i just replaced the thermopyle yesterday..
my problem is this, the unit will light and run for about 5 minutes.. I followed the raypak trouble shooting flow chart that came with the manual, i have jumpered all the connections, individually and at the same time, with the same results.. i have a good piolt flame, and the burner flame is a solid blue..
Any ideas what the problem might be? I was leaning to the gas valve, but with all the jumping, the valve seems to operate as it should., also, it is a robert shaw valve if that helps...
thanks for any help!!
