A/C Help

Having a heat wave and our AC decides to give us a problem. The unit turns on but just blows warm air. What is the issue?

Is it possibly frozen up?

Seems as if the compressor can’t kick in.

Welcome to IRV2.. have you had normal yearly maintenance ? How are you with electric and circuit ? Do you have some basic electrical testing tools? Sorry if theses are difficult questions.. but I would not like you to get killed or injured or set rv on fire.. basic.. test .. volts at pole or gen.. we need to know the make, model and year of coach and chassis.. and are you asking about roof top, dash or basement a/c... then you will start to get some great opinions..good luck and let us know what you did and maybe better members then me will help you

Probably a bad capacitor. High air temps. are hard on capacitors. Replace with one of a little higher rating. Usually a bad capacitor will be bulged at the top/and or the whole can.

Just remember even a bad cap can hold a charge even when the power is removed. Careful you don’t light yourself up, especially up there on the roof in your flip flops.

It is the roof AC, appears to be front and rear! We have a 2014 Allegro Red. We haven’t run the air in two weeks and all was fine then.

When it rains it pours.

Just posted a new thread on this issue. One AC need new capacitors but the front AC needs to be replaced.

My Tech has been looking fir three days with no luck. Looks like 2-3 month wait! Tough when on the road.
