Our 2002 Keystone Sprinter 28'fifth wheel with a single AC has been freezing up. It has happened before when we were in high humidity areas but we are in UT where the humidity rarely gets to 20%. Even before it freezes up, it doesn't seem to cool like it used to. It has been getting to the low 90's here but the AC will only cool to about 83-85. It seems to put out cool enough air in the first few hours and then the fan output lowers as well as the coolness; I suppose as it starts frosting up.
Does this mean it's low on coolant? If so, can I test this with the coolant refill gauge/attachment I use on our vehicles? Can coolant be recharged in these units?
Any other suggestions will be appreciated. We are in UT for another 2 months of hot weather:)
35,000 BTU is a bit of overkill to say the least. So my guess would be that you're attempting to throttle the A/C by keeping the blower on low speed.
Turn the blower speed to MAX!
