Kubota LX3310 Cab AC Went Out

[carr5600]

Hello,
Does anyone know if my kubota insurance cover fixing the ac? My tractor was delivered November 2021, so I’ve had it for two and half years. My dealer did maintenance on the tractor a couple of times. But i am here in orlando florida and the temperatures have been in the 90’s luckily the humidity level haven’t been as high as in the summer months. I use the tractor mainly to muck horses and cow stalls and dumping in compost bins. I paid for the kubota insurance but i never received anything on the insurance other than my orange package. So does anyone know of this is something thats covered?

No, not unless something like in an accident or peril that caused it to not work, like a jammed a stick through the AC condenser, an alligator chewed up the AC lines, or one of your latest hurricanes drowned it.

KTAC does not cover mechanical breakdowns.

That is either a Kubota warranty issue ( if it's in warranty ) or you'll have to pay out of pocket.

Or put a stick through the condenser

verify your insurance coverage first!

What exactly is going on with your AC? A little more information about what exactly is happening and people can give you advice on how to proceed. Sometimes it’s a simple fix that you can do yourself. Other times it requires someone who is trained on AC’s.

I agree with BAP. Could be something simple save you a whole lot of money. Being a 2021 shouldn’t have enough hours for anything to be wrong. Check the belt tension, it will have its own belt that runs the compressor. Also check that that compressor clutch is working correctly, it will have 3 round rivet looking pieces on it. When you push the a/c those should be spinning. If not locate your fuse. Might be simple fix also check your condenser could be dusty/ plugged

No AC cooling could be caused by clogged condenser or low refrigerant or loose AC compressor belt to name a few of the simple reasons.

So just noticed today when I put the throttle on high rpm the AC starts to blow hot air when I place it back on low it gets cold again. What could be causing that?

Moisture in the A/C system can cause freeze-ups.
A/C work in challenging environments like Florida require careful evacuation/recharge procedures.
Perhaps a evacuation,replacement of the receiver/dryer,and a recharge is needed?
Good Luck-it's hot out there!

Pinch off the heater line coming off the engine block and run it. See if that changes anything. Heater valves leaking by are a chronic problem with tractor of all brands in the AC system. When the heater valve leaks by, it causes the AC system to not work properly and basically shut down. The heater valve is in the cab and the easiest solution to fix it is to put a shut off valve in the line near the engine block. You can pinch it off using a couple of small pieces of something flat and a pair of vise grips. Run it for an hour or two and see what happens.

Ok thanks. I will try that.

Report back what you find out.

I wil. Trying it this weekend.

So it did not work but found the problem. After the engine starts to heat up or when it’s really warm out there was a high pitch noise which I thought was probably a belt. It was the AC clutch on the compressor turning off. So off to replace that now.

It might be cycling off and on because of pressures exceeding the values of the switch on the compressor. Modern air compressors have high and low-pressure sensors mounted in the system. You need to properly diagnose the system to know for certain exactly what is the problem before you start replacing parts. It can be as simple as a dirt-clogged condenser or evaporator coil. Have you put a set of air conditioning service gauges on the system, and if so, what are the readings? You are not the first person to have air conditioning problems on a tractor, so learn from others and read all the posts on these forums to learn.

Yes the guages were place on it yesterday. The low side was reading 50 psi and it jumped to 70 every time the clutch stopped while the engine was running. The high side stayed at 240/250 psi the entire time. When I drove it the high pitch would get louder and the AC would start to blow hot air again.
