    Question about AC soft start

    After reading Neal’s post I thought they were only if you were using a generator. If they will prolong the life I’m all for that. I’m not super good at these things so how hard are they to install? I have a Dometic.

    Resolved Soft start

    I acquired a soft starter earlier this week. Yup I don't really need it, but I discovered a problem I thought I would share. No matter how I tried to search this forum I got (0) results on the topic. Seemed strange to me because I was involved in some of those topics. This post is a test...

    Pretty sure the PTCR is on a hard start, not a soft start.

    New A/C install - Soft Start Recommendations

    ...few instances where breaker has tripped when A/C + fridge & other powered items were run at he same time. So I am thinking that adding a soft start module would be a good idea. Can anyone recommend a make/model suitable? I see such a wide range of soft start units that say "they work for...

    Yes, mixed up terms.

    Well what I poorly conveyed is that I meant an actual soft start, such as Micro-Air vs a hard start capacitor that some will argue is the same thing.

    What is a (false) soft start?

    Still needed the new capacitors if they were the issue a soft start would not have fixed it alone.

    Sorry, didn't see that. The soft start usually starts the fan first then kicks in the compressor. My Easy Start uses the fan and compressor capacitor.

    Can you wire it back to original without the soft start to see if it will run?

    I didn't keep the original parts. I have another soft start on the way and I'll check the components tomorrow to see if there are more capacitors and get numbers off of them to order and make sure the fan motor spins freely which I believe it does.

    Resolved Air conditioner kaput (Dometic Penguin II 15K BTU A/C + Heat pump)

    I'm using a MicroAir Soft Start I installed years ago. I wonder if I should replace it? Chat GPT had me put the unit in fan only mode and put that on high, the fan did not blow. When it's in cool mode it seems like it's cooling, just not blowing. I'll get on the roof and see if the motor spins...

    Which capacitor? How many are there? Is this the soft start or some other?

    Easier to just get a multimeter that will test microfarads and test the capacitor.

    I believe there are two, if I remember from the Newmar Academy correctly. Let me see if I still have my notes and will post the numbers for them.

    Question about AC soft start

    There is a falicy concerning what a soft start can do. It is true that start current is drastically reduced. It is also true that start torque reduces when a soft start is employed. In turn if there are any loose windings less movement will lengthen winding life. Less start shock will lower...

    Question about AC soft start

    I will always have soft starts on my RV A/C's - I think the consensus is the A/C's do last longer with them. Yes, it reduces the startup shock for generator but also could allow you to run two units on 30A supply where you couldn't without the soft start. I had someone install my first one...

    ...scheme that reduces the locked rotor condition that can demand up to 10 times the rated run amps.(amps on label). Ultimately even with a soft start on your A/C it will still need rated power to keep running. Put simply? If the 30 amp power supply needs to supply more than 80% of it's 30amps...

    A/C soft start units

    Looking for info from those that have installed soft start equipment on their a/c units. I know @Neal has and I pm’d him but thought it might be worth asking the group about their experiences with these units. There is a company called Softstart that is advertising units at $50 off and free...
