    Hard start and PTC soft start

    I was wondering if soft start can be replaced with a hard start kit I think the name is PTC start assist on a Manitowoc I paid 80.00 dollars for this little capacitor and it’s getting hot or some reason checked amps perfect has any one tried to change this any thoughts or facts

    It may be OK to use it temporarily until the proper part is installed. It is normal for them to heat up after first use. They work fine the first time then not as well after they are in the circuit. They will work OK again after the unit is off and it cools down again. They work better when there is a delay on make timer. Why was the original part replaced? That is pricey for that part. Not really the best choice for ice machines imo.

    It seems to be an original part I don’t think it was added

    If it's an original replacement then it's fine and working normal. That would explain the price for it too I guess. It is probably just a PTCR. You can search for it here or google it for more info but it sounds normal for what you describe. I imagine it looks like a little keg right?

    I would wean yourself away from using the terms "hard" and "soft." They don't really apply as you have used them.

    Typically, a "hard start kit" is for a compressor that is hard to start. It is not a reference to the start components.

    Both PTC and either potential or current relay setups are "start components," but the PTC is a cheap approach that has a VERY long cool down time after the initial use until it is able to assist in starting the compressor again. A potential relay works each and every time it is energized. Current relays have largely been replaced by the cheap PTC devices.

    The better idea is to say "start device," and specify the type being discussed.

    A "soft start" refers to a type of VFD drive that slowly begins to rotate a motor by ramping up to the prescribed operating speed.

    They were called soft starts before vfds were invented

    I think there is some confusion in the industry concerning start kits-devices. Just because a company labels something a "soft start" doesn't necessarily mean that it is one imo. I don't know if you have 20 years in or are somewhat experienced with fewer years in but many in the trade will judge you in how you phrase things. Just the way it is. I think you may find the link below somewhat informative. I don't think it addresses the vfd drives TB was rightly talking about.

    It's a ptcr and it's supposed to get hot. It's not a capacitor, it's a relay that drops out on resistance created by heat.

    I don't know about that, I read that as a question as to why it was getting hot.
