Kelvinator KFU09M2 FREEZER (Made by Frigidaire) PTC Replacement

[fobicboy]

HI,

I have a small upright freezer with a bad PTC. The problem is the unit is integrated with the capacitor and overload.  The whole assembly part number is 216008900.  This motor starter has been discontinued.  There are a few available but the vendors are profiteering, pricing the assembly more than the freezer's value. My hope is to put together an alternate more affordable starter.  Unfortunately I do not know the compressor's HP, it is an Embarco EM55 SC, to me it looks like it is 1/3HP or less. The capacitor is a 12uF and the overload is a TM4 type, both components are testing OK.

Does anyone know of a replacement for this starter?  Perhaps a 3 in 1one or a PTC that will plug into this compressor?  I have attached a couple of pictures of the compressor and motor starter.

Thank You for your support..

Does the compressor winding ohm out ok? My kinda universal start device is the whirlpool 8201786 kit. Just have to get the right size terminals or get a pigtail from a donor refrig.

Frigidaire 5304491941 kit has the pigtail and should work.

Vance,

Thank you very much for your suggestion.  I will check availability of this part.  The windings ohm OK, I get about 5 ohms for each winding when measured between common and the other two pins (S&M).

 I was hesitant to use a 3 in 1, it seems that on PTC type starters the 3 N 1 does not play well with the compressor.  I will give it a shot and let everyone know if it works..

Believe supco makes version that is just a universal start group the is not a hardstart like the 3 in 1.

By about, what do you mean - the start windings should be about 15-20% higher Ohms then the RUN/M windings.

If the both the START and RUN windings equal 5 Ohms then you may have a problem with the start or run windings being maybe partially shorted to each other internally.

Did you do an OHM check between the S & M (Start & Motor/Run) and see if that is equal to the C-M and C-S added together?

First I would like to thank all for the support.  To answer Willie's question, yes both coils had the same DC resistance of about 5 ohms. Together it jumped to about 11 ohms ( between S &M) which was the sum of each winding.  This is an old freezer so you might very well be correct  about the partial short.

I received the kit that Vance recommended and used the new PTC and the original cap & overload. This kit was for a 1/4HP -1/3HP compressor, mine is about 1/7HP.  Had to make some jumpers but the freezer cranked up and is currently at temperature. Hopefully this is the fix.  While things were cooling down the compressor got pretty warm, one could not touch it continually without getting burned. I figured the thermal overload might kick it out but it stayed on.  This morning I measured the temperature and it was at my setting.  Going to let this run for about a week before I declare it fixed.
