Operating instructions i have a 30 year old house with a carrier 4 hp ducted air cond system. is there any operating instructions i can download? on the controls it has EM/HT switch ? is that for a/c or heating? regards, ken

It sounds like static electricity being generated through the filters. I suggest you change the filters and see what happens!

Please see my tip at http://www.fixya.com/cars/r5929960-s_thermostat . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

1. Remove the air cleaner intake duct.
   
2. Partially drain the cooling system.
3. Remove the radiator inlet hose from the thermostat housing.
4. Remove the thermostat housing bolts.
5. Remove the thermostat.
6. Clean and inspect the thermostat housing gasket mating surfaces.
7. 
   

To install:

1. Install the thermostat.
2. Install the thermostat housing.
3. Install the thermostat housing bolts and tighten to 18 ft. lbs. (25 Nm).
4. Install the radiator inlet hose to the thermostat housing.
5. Install the air cleaner intake duct.
6. Fill the cooling system.
7. Start the engine and check for leaks.

5 flashing is ' compressor drive' and check the high pressure, condenser fan motor capacitor for proper running

You need an electrician be careful

visit this web site..this should be very similar to your remote.. http://www.abergas.co.nz/anytime/pdf_files/anytime48b23cc130447p314.pdf

if the duct work is to small the unit cannot get enough air flow and will shut down on pressure faults.

Well Steve

The fact that it was cold shouldn't make a difference if the service tech knew what he was doing. ok now as far as getting it to work correctly. before you start any work on this thing. please dear god make sure the power is off to it and you check it with a multi-meter. just recently i got lit up by 480 volt 3 phase. 3rd degree burns on my arm and hand and many other things. so please cut the power off at the braker. ok you want the wall mount in a central location about eye level or just under. the universal highth is 5'5 but its all up to you. another thing you can do is change your remote to an all electronic one. you can pick one up for as little as 15$ most are simple though some can be a pain. also make sure that both the evap coils and condenser coils are clean. ensure that all fans are working corectly and that your compressor is pumping right. unless your pretty AC savvy you will have to have a tech come back out. the bad thing about AC systems is its never just one thing. good luck hoped this helped you

This unit was manufactured 1/8/00 and is a 4 1/2 system

Either its not drainning mositure properly or low air flow across the "A" coils- caused by dirty filter .

The model numbers change.You have a 3 ton system.The make and model that you replace it with is not nearly as important as a quality install.Do your homework on picking a contractor that you can trust.Have them do a load calculation to make sure a 3ton system is right for your house.13 seer is the minimum you can get.You need to weigh the projected annual savings of higher seer units against the added cost of having them installed.Again,get a contractor you trust and go with the best warranty.None were stupid questions.
