Furnace firing up once heated up hear a click but blower not kicking on. Already tested blower and it is working


No voltage at blower when you hear the click? Have you checked the blower door switch? i would think that would stop the whole thing, not just the blower, but it's worth a check. Trace the wires from the blower back, checking for voltage. Must be a relay on a board, if that has AC in, no AC out when it clicks, you've found your problem.
