Older 3 ton unit. Split system. Power to fuse block, unit does not run. No noise, no smell. Model# 38CKO36300

run capacitor

you have condenser issue. check at outside unit for 240 volts to contactor and 24 volts to contactor coil.

Hi John, depending on the size, I would need the model number from the outdoor unit if it is a split system, you should have 400 cfm per ton of cooling. If you have a 1600 SQ' home, and a 3 ton unit, 3 x 400 cfm is 1200. It would be to small. There are 12,000 B. T. U.'s of cooling per ton. 2 tons would be 24,000 b t u's. 3 tons would be 36, 000 b.t.u.'s. Also, most contractors put lever dampers in the duct work that can be adjusted. They will put a red flag where the lever is and we can adjust the flow to balance out the house. I don't know where your ducts are, under or above, but with a good light find the crawl space and check it out. Get the model number and call it in to get the tonnage or send it to me and I will tell you. It will have a 024, 030, 036, 042, or, 060 in the number, MODEL number and figure like I told you above, 12,000 per ton. 060 would be a 5 ton. This will let you know if the unit is the right size or not. Please rate me on this and I know you will be kind. Thank you John.

PS CFM is cubic feet per Minute.

Hello WESLEY The unit mod# is 3 ton.If the inside part has an 048 number means together it produces 3.5 ton.If inside is 036 it is 3 ton together.If it is a split.If it is a package it is 3 ton.

Hi if you are looking at the indoor unit and this is where you see this flashing light, remove the panel. The circuit board is where this led light is. You will also have a 3 to 5 amp fuse plugged into the board. Look for a chart on a panel door. It will be glued there. It will tell you what the problem is according to how many times it flashes. Could be several different safety switches. Make sure there is no door panel switch on the indoor unit, has if there is, the unit will not run after you remove the panel, it kills power to it. You may need to tape it down so you can have power to run it and check it out. Is the indoor unit a gas system or is it a 4 ton heat-pump? If you cant find what I have said, get back to me after checking these things and let me know . Check all breakers. Let me know if this is a package unit or a split, indoor and outdoor unit, or all in one. I will wait to hear back from you on this.

Hi, yes the number you are showing me 036 indicates its a 3 ton unit. For every ton of cooling, you will have 12,000 btu's of cooling. 36 divided by 12=3 ton unit. Its showing me also its a Ruud Handler 2.0 ton which would be a Model# UACC-024JAS? If your mobel number is the one you gave me, UACC-036JAS, this is a 3 ton unit, absolutely no questions. I hope I have been of help to you. I am a licensed air conditioning / Refrigeration /Heating Contractor. Let me know if I have been of help.

PS If this is a split system with the indoor air handler and condenser outdoors, both coils must be the same tonnage for it to work for you properly. You can't have a 2 ton indoor evaporator coil with a 3 ton condensing unit.

The mfg. date is sometimes (depends of the brand and the size of the unit) on the serial number.And the 36 in the model number means exactly what you think 36000 BTU or 3 ton.

On your thermostat switch the system "off" switch the fan "on" and check for smell. If it still smells, could be fan motor overheating. This may be causing the outdoor problem.

Enter the name of the unit into your browser. It will ask for a model #. Enter that. All the info you need should be displayed. (I can tell by the model# your unit is 3 ton. Rule of thumb; 10 amps/ton Therefore 6.2 KW)
