Question about Heating & Cooling

1 Answer

I've got an air conditioner (Carrier 38TKB) that keeps blowing fuses (Bussmann FRN-R-50). It runs great after installing a new set of fuses but after a couple of hours it quits all together.

    Yes the fuses are rather loose in the holder. I never thought that, that would be the problem. Thank you I really appreciate your timely response.

In almost every case that I've dealt with concerned repeated blown fuses, if you can not find a short, it is usually the fuse holder itself. If the fuse is not VERY TIGHT in it's holder, it heats up and then blows. It is not always an over amping problem that blows the fuse. Check it out. Next time, see if the fuse is extremely hot. DON't GET SHOCKED! KILL POWER FIRST!

2003 carrier weathermaker 38tkb unit 40,000 btus 10.5 seer 3.5 ton - what should start amperage be?? is 132 too high tks

as you are running 2.5 or 3 mm wire for the unit , at 132 amps the wire would melt
check the setting of the amp meter as it is more like 13.2 amps which would be about right
use an example , check the size of the wires from a battery in a car and that size wire carries 400 amps minimum when starting a car, then check the wire size to the unit
all compressors start with a high current draw ( 25 amps ) but it drops of to running current after a 1/2 second or so

I need to know where the little fuse like thing is on the carrier air unit. Everything works but blows hot air. Had this problem before but do not where fuse is at.

The fuses you need to check are in a box by the outside unit... the wires from that box run into the outside unit to give it power...

Here is a tip about trouble shooting your air conditioner...

Carrier 38tkb not working, but furnace is blowing

It is probably a capacitor problem. Check inside the outside unit. you will see a round cylinder with three groups of terminals on top. If the top of it is dome shaped it probably needs to be replaced. You can check it if you have a microfared tester. However if it is poofed out it probably is bad. If this is not the problem you will probably have to replace the fan motor.

Furnace runs constantly since blower motor was replaced

Sounds like they wired it direct to line voltage , it should run through a sequencer or fan relay to cycle on and off , your seq./relay could be stuck closed to but unlikely being it was just repaired , call the service company back before you do anything they are responsible.

Fan circuit board on a/c is blowing

You have a short somewhere in your system. It could be anything from a thermostat, thermostat wire or any component in your system. Honestly, you are better off calling a tech.
