SOURCE: air conditioner doesn't blow cold air. Continues

If the a/c fails to continue to blow cold there could be a few problems you can look for. First once you activate the system check to see if the compressor kicks in. You will hear the compressor humming . Once the a/c quits cooling go and see if the compressor is still running. If its not running its probibly gone into thermal overload (compressor overheated). If that is the case then you need to check to see if the coils are icing up if they are icing up then the problem is with 1) air flow restriction filter dirty, coils dirty simple repairs there replace filter, clean evaporator coil with a coil cleaner that can be purchased at a home repair store cleaning the condensor coil the same. 2) system is low on freon in which case the system will need to be recharged. Also, If you have a digital thermostat replace the batteries that may also be of some help. Good Luck on repairs

SOURCE: What does the mode button do?

The mode button can be changing it from low speed to high or if it is a heat-pump, from heat to cool. Normally, its the mode you want to run it in, if its only an a/c unit, it would have to be low cool, med cool, or high cool. Its unfortunate you have misplaced the manual as it can come in handy for trouble-shooting in the future. I would go back where you bought it and say it didn't come with one.

Testimonial: "The reason I don't have the user guide is because I am a renter and when my air conditioner quit working, my Landlord replaced it with a brand new Kenmore and I really love it. I think he must of kept the user guide. Anyway, thank you for responding so fast."

A Google search turns them up pretty fast. Otherwise I recommend contacting your local authorized service center for assistance.

I need the 4 castors/ wheels for a Promac PM 38 CM

You will probably have to contact the manufacturer to find a dealer in your area that carries replacement parts or they can sell them directly to you.
