hi all,
i have been noticing my compressor coming on a lot more than it used to. i have looked for leaks till the cows come home and have not found any. used the fancy leak detector and all.
les posted about the air door can get stuck of the pin isnt lubricated.
so i thought i would go out and lube mine. i took the cover off and was sitting there with the door open on the steps inside. so i closed the door for some reason still sitting there. and i heard a hiss. i thought it was just finishing its close cycle so i sat a little longer. kept hissing. so...out comes the ultrasonic leak detector and i put earbuds in. it was leaking out the exhaust port of the MAC valve. only leaks when the door is closed. when open, nothing.
i called BODE and talked to their tech guy. the door is a BODE 3324.00
he talked to another tech and they both agreed that 95% of the time it is the mac valve that is bad or has something stuck in it.
the part number of the MAC valve is 45A-AA2-DDBJ-1JM 12v 5.4watts. i used my inspection camera to get in there and see the part number for the valve. the valve is the distinctive MAC Blue color with the white relay on it.
i found a new one on ebay for 25 bucks shipped (they wanted 35 and i offered 25 and they accepted).
i called and talked to Jim at Newell (their bode air door expert) and he confirmed that most of the time it is the valve. he asked if mine was a race coach and said that it could be the cylinder needs a rebuild kit if it had been opened and closed alot. the rebuild kit is 200 bucks so i will try the valve first.
both the valve and the cylinder can be done without taking the door off.
i will get the valve in the next week and try it. if not, i will get a rebuild kit.
les helped me to find the leak by getting me to go lube that pin.
