Evaporator Coil Leaks-Suggestions?
« on: April 05, 2010, 08:37:47 PM »
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.

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

Thanks man,

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.
Hope you find our website helpful.

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