I have two 630035.321 on my RV. The front unit iced up last June and an ac person came and put a valve on and refilled the R22. This year the back one iced up and soaked our bed under the ac. I then ran the front one and only had minimal cold air coming out of it. In inquiring about serviceing the units, I was told that the RV mfg. will not replace the R22, but only replace . I found out in reading my extended warranty that it appears this would not be covered. Even if it would be covered each unit would have a deductible. A $1000 deductible. UGH What do you recommend?

SOURCE: unit blows cold air instead of warm (burrrr)

FAULTS ARE STORED WITHIN THE CIRCUIT BOARDS MEMORIE TRY UNPLUGGING IT FOR 2 MINUTES AND PLUGGING IT BACK IN

SOURCE: no start up

No its not. Bad valves are caused by dirty filers,dirty coils that cause liquid refrigerant to slug compressor and knockout the valves. Rus

It's most likely an airflow problem, you say you had the vents closed? Icing up is normally caused by lack of load (air flow) or loss of refrigerant charge. Make sure all your vents are open to allow for as much airflow as possible and that your filter is clean. Some units do not work well on low airflow setting when the outdoor temps cool down at night.

Testimonial: "somewhat helpful.. I have had the AC unit on HIGH with the vents all open and same problem occurs. "

Hi,
No you can not use a R-410 air handler with a R-22 condenser unit...the exspansion devices are different as the properties of the refrigerants are enough different that they are not interchangable...
Really your only choice is to replace the whole unit as it sounds like the exspansion valve or the orfice is partially clogged and it makes you constantly freeze up....
There are some things you could do to make it work at reduced capacity but it is way beyond what I could tell you through a computer...

Hello
The ice buildup is an indication of low freon.The inner coil should feel cold and moist from the bottom to the top of the whole coil.

Before you do anything get a product called simple green degreaser and spray it on the inside and outside coils.Rince with a garden hose,try the unit again.Pay close attention to the outside coils.

If this does not work then the unit may be low on freon.Also be sure the t stat is on full cool.
