Novice here! Forgive the non-tech rambling! I have an old top freezer maytag ptb1753drw. The Relay Overload start device fried. I bought a replacement called a Kenmore Maytag Refrigerator Relay Overload Start Device, with 3 wire connections on one side and 3 receptacle holes that attach to the compressor. 2 holes are round and connect to the white and orange wires and there's a hole looks is like a mini jack-o-lantern smile with a round hole just below it which connects to the blue wire. The orange and white wire holes and jack-o-lantern hole were completely scorched. The blue wire did not fry so the round hole below the jack-o-lantern hole didn't fry so badly. I replaced the burnt flag connections and am ready to plug the relay onto the Embraco EGU 70HLC compressor. However, I am not sure what the prongs on the compressor should look like. 2 are plain round prongs and one has a weird rectangle piece of metal on the end. I don't know if it's supposed to be there or if it's from the guts of the fried overload relay. It looks rather melted. I found the 2009 thread: "Compressor Connections (Relay/Overload Protector)" thread and richappy's answer that "The start device may be arc welded to the compressor pins. Bust off what you can and use a dremel with grindstone to dress up the compressor pins." Is this what I'm seeing? Do I need remove it? Do I really need a dremel? Does anyone have a pic of the Embraco EGU 70HLC compressor prongs? Should they just be 3 plain round prongs? Thanks to any info and your patience for reading this through! confusedincc attached the following image(s):

Hey!!! Good news! I answered my own question!
Someone had a pic on ******** so I saw the prongs and see that metal blob thing is not supposed to be there!
I'm going to operate!!
I hope the patient survives!

Very good. Be careful with the damaged pin, the metal might be brittle from the heat, bust it off and the compressor is toast.

Thanks for the fast reply...
So you can see the little cap on the prong in the pic?
Would it help to try applying a bit more heat directly on that fused cap (like a hobby electric soldering iron) to get it off?
Or will that make it more brittle?
I don't have a dremel but maybe I have a grindy drill bit.
It's still in fridge and sideways...hard to reach. Do I dare undo 3 of the foot pins to swing it to me or am I begging for problems?
I am not a repair person, just too poor to buy a new fridge right now and somewhat handy. I'm also an old, arthritic dame so I need technique over brute strength.
Any tips besides dremel??

Yes, remove the compressor retaining clips and swing the compressor out so you can grind the bad pin.

Thanks for all the advice.
I couldn't pivot the compressor with the copper piping in place but managed to get the metal blob off, plugged on the new relay thing and have a 38º fridge and about 4º freezer.
It has cycled on and off a few times so I hope it's good to go.
