Who Can Diagnose This: Heater Keeps Blowing Cold

Mine goes to top on the matrix too

Seems fine now! I'm sure it was some air in the system.

 

Did a leak down test just to be 100% sure and its 6% on all 4 pots!

 

That, coupled with compression the same on all 4, no oil in the water, no water in the oil, and a pass on the sniffer test, points to air in the system.

 

Time to get back out and stop worrying!

 

Thanks for the help.
