Question about Air Conditioners
Can you tell me what the fault code "HO2" on an Airwell Air conditioner means?
I just purchased a 11,000 BTU Everstar from Home Depot. Not sure if it's the same model that you have. Maybe check there? I bet an employee would be willing to open one of the boxes to answer your question. Just tell them you bought it there. :) Or call Everstar, of course. Good luck!

Hello; Those roof tops can be noisy. Are you able to determine what is causing it? The fan? The A/C pump? Over tume, the vibration isolators that are rubber cushions the pump is mounted on, get weathered and hard and they no longer absorb the vibrations of the running pump. Those are easily chked and changed. The next point of excessive noise is the unit as a whole is tranmitting the combination of all the vibrating parts including its own housing. Here too we have a remedy. The roof unit has a seal between it and the camper roof around the hole it is fitted in. The seal is foam rubber and reasonably thick enougth to serve a purpose more than to seal out water and air. After and over time this seal ends up crushed from the weight of the a/c unit. Then the A/c unit comes in contact and is actually resting on yhe roof with what is now a very flat hard gaske. The roof unit is now vibrating the roof. This is as destructive as it is annoying. Ok? Now let's get rid of 80-90% of the noise. Check and replace compressor vibration isolator mounts. There are 4 bolts holding down the A/C unit. Sccess them from the inside by removing the ceiling trim and cover.There should be one on each corner. Bolts removed, one person push up on the unit and another on top lifting the unit. There are wires going to the unit and those may need to be disconnected. Clean the roof and the a/c where yhe seal goes.You can get a new seal from camping world or rv supply. Have your measurements, Unit make and model when you go.Assembly is just backtracking. On assembly, thinhs to pay attention to are:
Put the new seal on the A/C unit, not on the roof. It takes two people to ligft and set the unit back into the hole and center it in the hole. Don't slide it on the seal. lift it if it hs to be moved or the seal may roll over..
The wiring disconnected earlier must be dealt with and put in place for reconnecting.
Now start the bolts that hold the unit down.
Make sure-- Unit is centered
Wires can be reconnected
The four hold down bolts have their washers.
Someone go topside and verify the seal is properly in place. Measureing the for corners fo even height is one way to ck and looking under the unit is another. Now tighten the four bolts evenly. corner to cross corner. measuring again will help confirn its pulled down evenly. Pull it down no more than 1/4 to 5/16 of the seal thickness. Wire it up and put the trim and plastics back on and light it off. (run it and ck for noise and vibration. NOTE!!! The A/C unit cannot touch any solid part of the roof. Reason it was centered. Always ck the unit before each trip as you would any other psrts on the exterior of the camper. Good Luck Angie.

I havent had luck in finding a part list for you but have you tried to look at the label on the motor(s) to find the capacitance? Or try on the existing capacitor? Dual caps are usually listed as 35/5uf or 35/5MFD on the actual part. There are only a few variances of contactors for residential systems normally 30-40va single pole single throw (spst) or 30-40va single pole double throw (spdt) singe throw contactors have four contacts for 220v and double throw contactors have two contacts for 220v and a constantly hot leg.

Turn off the circuit breaker and wait 10 mins, then back on.
Turn off all units, wait a about 1/2 hr. See what that does. Also, Turn only one unit on at a time and let it run 5 min before turning on the secon and the same withe third. An what remote island might that be? Good Luck, Ned

SOURCE: air conditioner wiring diagrams
What brand of A/C is it? Are you looking for the thermostat wiring? Different Brands use different wiring, but the usual is as follows:
R terminal at furnace is 24 volt Hot
W is the control for the heating cycle
G is used to start the furnace blower
Y is used to start the outdoor A/C
B or X depending on Brand is the 24 volt common
Yellow and B or blue is the other wire that goes to the outdoor unit
If you want more info, I need Brand, and type of unit, gas furnace and A/C, electric furnace and A/C, or is it a heat pump for the outdoor unit?
Hope this helps./
