dash ac

Hi All: Ihave a 2007 ford chasis itasca 32 foot sunrise. The ac just quit working. It blows the air but itisn't cool. I'm thinking it should be a fuse. Lookingat themanual I can't find the right one. Any suggestions would be appreciated.

the # 1 cause would be low freon. You have a low pressure switch that cuts off the pump when low on freon. I would start there.

Not cooling could be many things...from any sort of electrical problem to low/no freon to warm air door open in the evap box. With engine running turn on the dash AC and see if compressor clutch is engaged and spinning. If so....then the electrical portion is fine. Next would be to check pressures and go from there.
