Mitsubishi WT-42413 issue

Hello, I have a Mits WT-42413 I can turn it on and it works just fine then anywhere from 15mins to 30 mins it shuts down. If I let it sit for awhile I can turn it back on. The blinking error is 2 3 Any ideas on what this could be and what would need to be replaced/repaired? Thanks for your assistance in advance.
