Ink Overheating on HP Indigo 5000

[H2Omark]

Having an issue with yellow ink tank overheating. I have cleaned out the lines to the yellow tank with air and replaced the solenoid. All three of the other colors are holding temperature just fine so the circle valve is working but the tank value on the yellow is not. When I click on them manually the temperature just keeps rising. I can run if I bypass the temp. on the yellow but need to fix this before I run into trouble. Is there a fuse or relay that I should be looking at? We are not on contract and have no service so it is just me. Thanks in advance....
