SOURCE: seal for roof top ac unit

I just spoke with the mechanic at my RV dealership and he said the sticky side goes on the a/c unit. You only have to turn it on it's side to do this. Just wait 1 hour after re-installing the unit on your RV before turning it on.

SOURCE: , Compressor start capaciter MFD value: roof top RV Dometic unit

Hi, I did some research and found nothing on the a/c unit. If I had the model and serial numbers from the condenser and compressor this would help me. This would be a run capacitor doing the start up, dropping out the start relay and keeping it running. If you have only one run capacitor and its a dual, will have 3- female spades coming from the top, with marks that say Fan, C for common, and Herm. for compressor. If it has only one capacitor with2- female terminals, several places to connect more than 2 wires, its a single cap. If it just runs the compressor, it could be a 370 volt x 20, 25, 30, 35, uf?? If its a dual it could be a 370 volt x 5 u f for the fan and the same , 20, through 35 u f or microfareds. The best way to find out is to take off the wires on it, and make sure you draw a diagram so you know they are right, and take it to a appliance parts house and let them check it to see what they are. Larger units can have a 440 volt x 20 to 35, 40, 45 and so on. Your unit is not that large, so it will only be 370 volts as far as voltage, but the u f value will need to be checked with a meter that will check the value of these and give you a number such as 4.99 u. f. and you will no its a 5 u f. It may be higher like 5.24 u.f.and that is OK. Make sure the capacitor has no oil leaking from it or its not swollen looking or distorted in anyway, it will be open or shorted out. Please let me know if I have been of help to you when you go to rate me, please be kind. I will be here if you need my help if you are having problems with the compressor not starting.

PS If this capacitor is black plastic and mounted on the side of the compressor, it will be a start, run capacitor with 2 wires. It snaps in a metal type holder you will need to take it out and check the terminal area it was connected to and remove it. If only 2 wires, it won't make a difference what side the leads hook to.

I have a kenmore elite , Mod# 71203100 mfg=10/10/2001 it worked fine since I got it ..48 hrs ago it was found to be not cooling anymore, lights go on fan's work , but compresor will kick in for 30 sec and...

I would fix it because The way I am understanding the compressor is getting hot and thermally kicking out. This could be a thermostat or a start relay for the compressor. Or it could be low on charge that will also make the compressor shut down because of the head pressure. I would check out my thermostat really close and any start relay's for the compressor. It would be about 200.00 compared to 1200.00 to replace it.

The compresor wont start and it's getting very hot!

Check the capacitor. It is in the outaside unit. Siver with three terminals on top. If it is swollen it is bad. Check for burnt wires. You can repair these yourself. Compressor maybe stuck. If it is an old unit you will have to replace it. Rusty

Freezer or fridge stopped cooling. Can not hear compressor kick on

If the compresor is trying to start and it won't you 'll heard a click and the compresor will be very hot ,that means that the relay is bad or the compresor is stuck or burned and needs to be replaced, but first before replacing the compresor try with the relay (no more than $20).But if the lights and fan inside the fridge work and the compresor won't start and is not hot ,the problem is in the cold con trol (you can put a jumper wire between the two wires to the cold control and if the compresor starts thats your problem) after all this if still the compresor won't start could be that the timer is stock in the defrost position.

This is a typical symptom of having an A/C system low on freon if it cycles on and off when first turned on or very soon afterward. All types of A/C units for home and auto have a low pressure cut-out switch that will disengage the compressor when the freon level drops low enough to cause damage to the compressor. The unit needs recharging with the proper amount of freon to correct the problem. If it's an automobile A/C system and the freon level is okay, it could be a faulty compressor clutch or coil.
