Troubleshooting FAQ
How do I know I installed it correctly?
EasyStart has a few characteristics that can help you determine that. First, the compressor
should start more quietly than it did before. Lights will dim much less and if you have a volt or current
meter you should see a measurable difference.
Second, if you turn off the compressor at the thermostat when it is running then turn it on right
away, EasyStart will prevent the compressor from starting for five minutes. If the compressor starts
sooner, you have a wiring problem.
Nothing works, not even the fan.
EasyStart does not affect the fan at all. If the fan does not run then most likely you connected
the wrong white wire to the brown wire. Check it again and make sure the wire connected to the brown
wire is the white wire that comes from the compressor.
The fan runs but it won’t start on utility power.
1.
Go through these directions again and verify every connection.
2.
Be sure you turned on all the power you turned off. Some thermostats need DC to operate
as well as AC.
3.
Check the thermostat set point. If you have a digital thermostat the ambient temperature
must be above the set point for the air conditioning to work. If it’s a slide thermostat, it
must be set for full cool.
4.
Is it too cold for the compressor to start? We often get calls where a slide thermostat will
not work under 70°F (21.2°C) ambient. Try heat mode if you have a heat pump and it is too
cold or warm the RV with the heater first.
5.
Check your line voltage when the compressor tries to start and make sure it is not dropping
below 108 VAC. Some RV’s have surge suppressors that cut off on low voltage.
I did everything in the last FAQs and it still will not start. What next?
Go to the Micro-Air.net website and download “Advanced EasyStart Troubleshooting”. Follow
the steps given to determine the possible problems.
My air conditioner runs great on commercial electric power but will not start on my generator.
Be sure all the loads are turned off in your RV. A 15K BTU air conditioner will use about 1800-
1900 watts to run leaving no additional capacity for any other loads on a 2000-watt generator. Be sure
you check generator reviews before you chose a generator. Not all generators can run an air
conditioner.
My air conditioner shuts off early on generator. What can be wrong?
Aside from the suggestions in the last questions, you should also test your generator output and
verify the RV load. We offer a generator test kit on Microair.net. The associated manual is available from
the test kit purchase page and has the complete test and additional things to look for.
