Turck : 97 Ford F-350
Just added a new "low pressure switch" to get it working. Charged it to 45 which the dial said was a little high but still ok.
Shouldn't it be better than every 10 seconds?
Please help! It's hot and it is barely cooling.

The switch is cycling every 10 seconds because the system is low on freon. Best to evacuate and recharge the A/C and be sure to add dye so any leak in the system can be found

The low the fan speed the more the compressor clutch cycles. The less freon it has the more it cycles. If it is full of freon and you keep the a/c on max, blower on high, and it still cycles, the system is stopped up. On some cycle switches you can adjust the cycling, turn the screw inside the switch, one round counter clockwise. Also make sure your radiator fan is pulling air.

Not so sure why you added a low pressure switch but all symptom's lead to not enough Freon in the system. If you are sure it has enough Freon then you have another component of your A/C system that is bad sounds like its time to take to the professionals and not your local oil change place probably back to the dealer.

was the system empty to begin with? if so did you vacuum the system with a suitable vacuum pump for at least thirty minuites before charging? and did it hold that vacuum for at least ten mins.?did you charge with the exact amont of freon? and have no pipes freezing(icing )over? then you probably have a bad cycling switch.
