Troubleshooting Your SoftStartUp

  1. SoftStartUp has a green lamp in the plug housing that can help you determine current is flowing.

First, the air conditioner compressor will start more gently than before.  Lights will not blink or dim a smaller amount. 
Second, when you turn off the air conditioner compressor at the thermostat control when it is running then immediately turn it on, SoftStartUp will prevent the compressor from starting for approx 3 minutes. (This is to give the Compressor time  to equalize). 

Perhaps you have other electrical loads going on. Try turning off the refrigerator, backup battery charger, microwave and other appliances. Start the A/C. When it starts, then gradually add other appliances. If the generator cuts out on the last appliance added, you know that one took the running AMPS over the top.  It may require a little juggling of appliances and electrical “loads” to see what possible and needed for your situation.

  1. Run through these directions again and make sure all other appliances are turned off, including your standby battery charger.
  2. Confirm you turned on all the power that you turned off. Certain thermostats require DC to work as well as AC.
  3. Verify the thermostat set point. If you have a digital thermostat, confirm the temperature must be above the set point for the air conditioning to work. If it’s a slide thermostat, it should be set for full cool.
  4. Is the ambient temperature too cold for the compressor to start? Many RVers share with us that a slide thermostat will not work under 70°F. If so, test the heat mode, if the RV has a heat pump – and it is too warm or cold.
  5. When the compressor tries to start, confirm your line voltage and confirm it is not falling below 108 VAC. Various RVs cut off on low voltage because of surge suppressors.
  1. First, ask yourself some questions.  Did your A/C function prior to this install?  Do you have sufficient power? Some generators boast 2000-watt when they only put out 1800 to 1900-watt.    Did you attempt to re-start the A/C within 3 minutes of the last start? The unit has a built-in 3-minute delay timer, allowing the compressor to equalize.  After that, contact us via email: support@softstartrv.com and try to detail the steps you took. Then email them to us so we can get up to speed with your situation as soon as possible and help you with a solution.  Be sure to indicate the make and model of your A/C.
  1. Confirm all the loads are turned off in your RV.
    A 15K BTU air conditioner will use about 1800-1900 watts to run causing no additional capacity for any other loads on a 2000-watt generator. 

Confirm and check generator Google reviews, before you buy a generator. Not all generators can start an RV air conditioner. Not all generators have the running capacity they advertise!  The original “standard” RV Generator was the Honda 2000. That typically is not enough power for today’s modern RVer.  

  1. Review all FAQs, test your generator output and confirm the RV load. The generator FAQ troubleshooting information and questions are on the website.
  1. Follow the steps outlined in the directions you received in your shipping box or go online to https://www.SoftStartUp.com/instructions

What Appliances Can I Run Simultaneously?
RV Appliance Operation:  Amps x Volts = Watts

AC Compressor                 8.5-11.2A*    980-1300 watts*
AC Fan                                 2-3.5A*            230-400 watts*
Converter/Charger         5-7A*                575-800 watts*
Refrigerator                     4-12A*            460-1400 watts*
Water Heater                   9-13A*         1000-1500 watts*
Toaster                              6-10.5A*        700-1200 watts*
Hair Dryer                       13-17A*        1500-2000 watts*
Microwave                       5-10.5A*        600-1200 watts*

*Consult the individual appliance data plate for exact amps/watts
*Review the Amps/Watts you have available vs the Amps/Watts of the appliances you want to operate

e.g. If your A/C compressor is running 1300 Watts and you have a 2200 Watt Generator that RUNS at 1900 watts
then you only have 600 Watts available with your A/C running on 1300 Watts.

IMPORTANT NOTES:
– A 2200 watt generator normally provides around 1900 running watts
– Heat increases the amps/watts of some appliances and decreases the performance of your generator.
– Extension cord length and wire size affect the amps/watts – the shorter the cord and larger the wire size the better
– Altitude decreases generator efficiency by an estimated 3.5% per 1000’ of elevation
– Fuel source affects generator efficiency

Got a problem and need live support?  We are here to help.

 

First, take pictures of the wiring diagram of your A/C usually found near the unit, once the cover is removed. Second, take pictures of top of the compressor and the top of the run cap, both showing the wiring. 

 

Send them via our support ticket system here. 

 

We will try to get back to you within 1 to 3 days, it depends on our support volume and how many other customers are waiting…   

 

It is more efficient and easier for us to get answers to you quickly, if you send your wiring diagram and wiring pictures to us first via the support ticket system, and then allow us to respond.
