Evaporator Coil Leaks-Suggestions?

[DaveTech]

I have a question I would like to ask about the evaporator coil repair. My question is how do you repair pin holes in the aluminum coil, besides apoxy? Do you suggest any special brazing aluminum rods; any numbers or names?

Thanks,

DaveTech

I'll ask my buddy tomorrow, He's a welder in the union. Also the one who put my appliance cart together. If anyone would know, it would be him.

You cannot weld the evaporator.

Yeah I know we can't weld it, but we can braze it. I need to know the aluminum rods.

Thanks man,

iv'e been  after my 9 service calls today.  J Dub is right, no weldin, lol, but still, he has alot of experience in welding, brazing, and  soldering.  I will still ask him tomorrow what he would suggest in regards to taking care of a pin hole in some super thin aluminum.

They do make a green stick. You heat it up and dab it on the hole. Its TO119 in this Pdf

although, what prevents more pin holes anywhere else in the (thin) Evaporator ?

I would replace the evaperator and be done with it. I have never had any luck with the apoxy repair kits and I just can't ever seem to braze that thin stuff.

Replace the coil, bill it out and be done with it.

Ah ok thanks.

Usually the hole occurs in a corner near the heater. This green stick is very effective in repairing that kind of leak.
