I just replaced my two 620315.321 shrouds with the newer style without any problems. I went to the Camping World site (and called them) with model no. and they knew what to send me. I also found that they had the best price at $79.00 (member price) with free shipping.
I didnt check your shroud part no.s, but think you will be ok if you do as I did.
If you have any question about installing, you can email me at firstname.lastname@example.org

Take it off,the plastic inside vents, with soap water and a hose wash it. Outside condendor and inside evapator, making sure the drain is open and outside shroad removed, brush off fthe loose stuff. wet both units, put liquid dishwashing soap on both. Spray then through , with a hose untill they rince clean. While up there. Oil the motor if possible. Keep the drain clear and open,making sure none of the water is getting into the RV.

Depending upon the model of your air conditioner, this may be normal operation.
My newer Dometic air conditioner will run the compressor in a "reverse" mode without the fan occasionally in order to heat the coils. This is done to defrost the coils. After the frost is gone, the fan switches back on and everything goes back to normal.

not likely but possible. if they already had one bad board what's to say their production methods have changed since they made your last bad board. I have just had 6 bad compressors from this chinese company danfoss in one month! for only 2 freezers i have installed 3 bad compressors in each! nobody takes pride in production anymore they want the stuff to break.
