I have worked on vehicle air conditioning systems since I was 13 yrs
old. That is about 52 years. I have seen a lot of crazy problems
and fixed every one that I was asked to work on. Having said that,
I am stumped. The TS110 money pit has always had a great air
conditioner. a couple of weeks ago I was cutting hay in a field a
little ways from home, so I had the atv to travel back and forth in
case of breakdown, etc... I baled for about 3 hours, then stopped
for lunch. I returned and started the tractor and noted the a/c was
not working. The compressor was not turning. I tried many
different thing including bypassing the low pressure cutout that had
been replaced a day earlier. It finally started working after I had
the doors open to the wind and the interior of the cab cooled off.
This took about an hour. It worked fine. I put it in the shed. 2
days later I had to bale another field and got started about 1pm.
It was hot and the A/c would work for about 2 or 3 minutes then quit
for 10 to 15 then run just a little then quit again. I spent the
next 3 hours in a 95deg greenhouse. I spent last Friday morning
checking the freon levels and the switch connections. I found the
air filters were really badly plugged. I found the only ones were
65 miles away and got them. Without the filters the A/C worked fine
and had the correct pressures for a R134 system. Today I got
started baling about 10 am and baled until 5pm and only once was it
blowing not real cold, but other wise worked fine... Later this
evening it was starting to rain and I went to back it into the shed,
the interior of the cab was hotter than a 2 dollar pistol. The A/C
would not blow anything but hot air. The heater does not work on
this so, it is not heater hoses. When the interior is hot, the
system will not get started.... I am thinking a high pressure
cutout switch. I really hat to bypass things, but I have seen so
many NH tractors at sales of this vintage that have an extra switch
in the cab for turning on the A/C clutch, I think maybe it is a
design defect as there are so many...... Anyone had any experience
like this???<br>
