The one we tried had pretty good cooling, but needed plenty of fan speed.
check the radiator is clear.
is the temperature on buttons or a knob?

Icing up or temp sensor in the evap core is failing causing the compressor stop or a gas leak. But as above dust out your cab filters and make sure the evap core isnt gummed up with dirt.

More info please... Do you get plenty of air flow through the vents? Is the air warm or ice cold? How often does the compressor cycle? Any bubbles in the sight glass on the drier when running?
Mostly its one of these, work through them in any case:
1) evap blocked with crap
2) cab filters blocked
3) fan or ducts got some problem
4) condenser blocked
5) engine fan viscous coupling partially failed
If above all good, move onto:
6) low system charge
7) air in system
8) moisture in system
9) defective thermostat or expansion valve.
10) compressor worn out.

Having a similar issue with 724 at the moment, dealer talked me through recalibrating the air con but doesn't seem to of improved it. Think it probably needs re gassing again.

Air con in mine is good. Haven't had problems with it being too warm. Have a word with your dealer I have also heard of systems being re calibrated.

Id imagine you have a leak on the hot water valve for the heater letting water leak round the system and keeping things warm rather than completely turned of stopping warm water getting into the radiator for the heater,if you see what i mean.i had this priblem on my john deere last year and yes we get problems with them too

Should of got a zetorIt's been recalibrated numerous times,I just wanted to see what others were finding.
I will get dealer to it again,they can replace the shite spool couplings for a 3rd time while their at it.

400 series. Try an Australian summer in one. Heap of s**t. Yanks no how to build an ac. 7210 magnum and jumper on on a 45°c day.It's been recalibrated numerous times,I just wanted to see what others were finding.

My 22 year old John Deere has the best air con on my farm by a mile.

Did you find what the problem was here? I drive on that’s doing the same .Anyone had a fault with the fan on these?
Stop engine turn off key and fan keeps on running,had to take fuse out to stop it,done it twice today.

Yes, the controllers often die.

Down here, where things obviously get hotter, it is common for a tap to be put in the heater line to turn off the water from going through the heater unit to help the ac function better. My MF 7620 came with it. And when I had issues with the controller in a new jcb tubby, the dealer quick fix was cut the heater hose and put in a tap. Works perfectly....Only pita is shoulder times of year when you might want heater on in morning and ac at lunch..
