MF7480 Climate Control

[Jinty Mcginty]

Air con was working fine yesterday then water started leaking out of roof, tasted to check it was not coolant but it was just water.
I assumed it was a blocked drain and turned the temp to warm and eventually stopped leaking.
Back in tractor today turned temp back to air con setting and the **** thing just blowing hot air at me.
The display all seems ok ie when you change the temp the degrees go up and down and air con light comes on but only hot air.
Tried switching the isolater off for a minute to disconnect batteries but no difference
Anybody got any ideas ?

Have you been in the roof to see if the condenser is chocked full of crap

No have not checked it yet ,whats the best way of cleaning ?

 

[Jinty Mcginty]

It was ice cold the day before so you would think if it was choked there would have been a gradual deteriotion rather than going from stone cold to hot in one day

 

[Lofty1984]

Try an air line it may not even be that it’s only a suggestion

 

[Lofty1984]

I’ve had it go like that on the standard air con not climate control the pipes freeze up can’t remember why now but if you turn the air con off for 5 mins it then works again until it freezes

Tried that as well but no joy maybe try an airline 2morro,anything than getting blasted with hot air!!. I think there must be a drain pipe choked as the water should not be dripping in at the dome light

Have you tried turning the tap off under the cab ?

Eh no wheres that
Dont say under the cab

 

[Lofty1984]

it’s under the right hand door as you sit in the seat the pipes come out from the corner post of the cab and one will have a tap on basically shuts off the hot water so you will have no heat in the cab I switch it off as soon as spring comes, might not solve your problem but it’s good to know about for future

Fair point everyday is a school day
Better to get blasted with lukewarm rather than hot air

Is the compressor coming in ?
Sounds like a thermostat problem if it was to cold it would have water every were

I would need to open door to have a listen (deaf as a post) if it is the thermostat is that part of the climate control module ,looks expensive !!

No it is a probe that goes in the matrix ,

Should you here it clicking by adjusting the temp like a boiler stat in the house

 

[Speedstar]

Should you here it clicking by adjusting the temp like a boiler stat in the house

yes , but with tractor running is it turning

 

[Lofty1984]

You will hear it click on when you turn the aircon on and off

Change the 2 relays behind the CC panel

Whilst we’re on this subject I’ve got a t2 7490 with climate control when working air con works fine when on tick over it blows warm air out as if the heater is turn on even with temp dial is on 19 but rev up again and cold air comes out
Proper strange one
