Hi all,

In the process of trouble-shooting my refrigerator issues (thread) I ended up taking apart the 3 n 1 start relay to see what was going on.

Big "well derrr" from everyone here I'm sure :) but for me it rang a bell with what the guy at the parts store said to me, "This will also replace your capacitor", and I thought to myself "but I don't have a capacitor...." which is true, with the model in the thread I linked above, I just had the start relay + overload components.

So anyway, I was trying to eliminate variables, and took the capacitor out of the equation to try to get everything as close to the original config as I could.

Runs fine like this. I'm wondering should I go forward with this configuration when I button everything back up, or should I add the capacitor back in? Does having a start capacitor help or hurt anything with a circa 2003 fridge that didn't originally come with one?

A start cap will destroy any pc boards but your machine doesn't have any. If the machine didn't use a start cap originally, a 3-IN-1 is a compressor killer. Leave it off.

Use of HARD START KITS on Electrolux refrigeration products has led to a number of reported fires in the machine compartment.

Older medium back pressure and high back pressure compressors used a start capacitor. They are wired in series with the start windings to supply more current for a longer period. That shortens the life of the compressor if it isn't designed for a start cap.
How would I find the horsepower for my fridge?
It's probably 1/8hp
