I just noticed today that my right fan on my EKO 60 is not working. The left fan is operating properly. I want to remove the right fan and capacitor to see what is not operating correctly. Is there any trick to removing the fan. Their are 2 screws holding the fan on the front that are easy to access, but their are two on the boiler side that I can not figure out how to access even with a long handled screw driver. Has anyone had to remove the fan before? Advice, ideas?
