1. SoftStartRV has a few features that can help you determine that.

First, the air conditioner compressor will start more gently than before.  Lights will not blink or dim a smaller amount. Use a voltmeter to see a quantifiable difference.
Second, when you turn off the air conditioner compressor at the thermostat control when it is running then immediately turn it on, SoftStartRV will prevent the compressor from starting for 3-5 minutes. (This is to give the Compressor time enough to equalize). If the air conditioner compressor starts before the time limit, this may indicate a wiring problem.

1. SoftStartRV does not affect the fan at all. If your fan does not run, then often times the error is most probably you connected the wrong white wire to the blue wire. Examine it again and confirm the wire connected to the blue wire is the white wire from the compressor.

1. Run through these directions again and make sure every connection.
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.

5. 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 double-check the wiring you created from the SoftStartRV, especially the 3-way or – in some cases – the 4-way splice?  Did you blow a fuse? Don’t laugh – it happens to the pros too. Replace it.  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. Go to Q&A #5 and test the SoftStartRV. Follow the steps given to determine the possible issues. Pay attention to #8 item 5. What are the LED’s indicating to you? After that, contact us via email: support@softstartrv.com or admin@softstartrv.com and try to detail the steps you took for the wiring you created and for the possible fix you did. 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.

1. Review all FAQs, test your generator output and confirm the RV load. The generator FAQ troubleshooting information and questions are on the website.
