I had my expansion valve replaced and the air was blowing cold/fine. However, after 3 days the EC light came on and I reset it several times. I was getting codes:e61, b1234, b1241, b1416

Any help with this and suggestions are appreciated. Thanks in advance.

6.195
7.17

When you had the expansion valve replaced did the technician do an overnight leak test? If not, sounds like a leak. EC light usually means low refrigerant level followed by EC light can't be reset and compressor won't run. Sorry.
