How to diagnose zone damper problem

Post by Glenn14 »

One of the zone dampers in my system is not opening. The controller panel is an EWC-OR-6 Ultra Zone. Is there a way I can diagnose the problem -- would it be the damper motor or the zone relay? I do not have testing equipment. Is there another way to isolate the cause?

You need a volt meter to test each circuit that is really the only way. Get a meter and call 1-800-446-3110-X490
