Thermostat Issue

dhlOASIS

I have a 98 FV330 and my A/C is out due to my thermostat. My thermostat shows AAA-17 on display and will not turn on. Has anyone ever had this problem ? What needs to be done to repair ?
Thanks !

Is it a Marine Air unit?

"AAA… Indicates failed air sensor. Unit will not run until repaired."

Yes it is a Marine Air Systems Unit. Not sure which model # it is. Thanks for the link !

I had the same problem a few years ago on my 330. Simple fix for me by installing a remote temp sensor. As instructed I put it in the return air grill. It simply plugged into the board at the AC unit. When plugged in automatically overrides sensor in thermostat.

NOT SURE but part # may be 222102307. AS I recall it was about $60.00
