Main cooling fan not operating. Cannot test to see what the problem is because the auxiliary water heater pump is not operating. Can this pump be removed from the cooling system?

Hello,

The answer is both yes and no. I have included in the diagrams down below the description and labor time for removal of the heater pump aux. I also included step by step factory diagnostic troubleshooting flowcharts for the cooling fans as well as the aux heater pump, which has to be installed and operating to do the cooling fans testing. Please get back to us with what you are able to find out, please.

Thanks,
Alex
