Comments about Generalaire 990-52 115 Volt Solenoid Valve Assembly:
The solenoid burned out on my valve assembly and searched all over the net,and local agenices for a replacement, inwhich I found out, individual solenoids are not made anymore to replace just the ones that are bad! One has to replace the whole unit! And the prices to replace this valve unit was hitting 3 digits, through (iaqsource.com)2 digits! Bought it, [...] installed it and it's working just fine!
