Frigidaire stackable dryer model# FLCE7522AW4 Serial #4E54100863 Runs for two minutes and then lights start flashing

Brand:frigidaire
**Model Number:**FLCE7522AW4
Main Symptom: flashing lights
What happens & when:

I purchased a new stackable washer and dryer. After a few months, the dryer would start and then stop two minutes later and start flashing red and green lights. It was still under warranty and Frigidaire couldn’t get a repair person to go to the area, so they replaced it. The new one did the same thing after just a couple of weeks. At this point I decided to do some troubleshooting. There is air coming out of the vent during the two minutes, and the machine started working when we disconnected it from the vent. Then it worked when we reconnected it, so we used it for a few more weeks and then the same thing started happening again where it would run for two minutes and then the flashing lights would come on. At this point, I had someone check the vent. There were a lot of bends (10), so we fixed the vent to get down to only a couple of bends. However, now the dryer is still doing the same thing. Frigidaire will replace it again, but I want to make sure we’re fixing the real issue.
Error Code (if any):

It would be recommended to put the unit into service diagnostics and see if there are any error codes involved. An error code will guide you to what the underlying issue may be.

Thanks for this feedback. I live in a remote part of Montana and can’t get a service person to come. Is there a way for me to diagnose the codes myself?

Here is a tech sheet that will help with the error codes.
