Product review (5 stars): Fixed 'blinking lights' problem on Frigidaire dryer model LEQ2152HSO. Dryer was stopping after 1 minute...
The Frigidaire dryer model # LEQ2152HSO was stopping after a minute or so of starting the drying cycle. The lights would blink and only after unplugging the dryer socket from the power outlet would the dryer reset. However, after some time, the dryer stopped running/drying even after unplugging the socket from the outlet.

I decided to gamble and figure out, through the process of elimination, the probable cause of the blinking lights. When the dryer was working, it was drying clothes and the drum was rolling, thus eliminating (in my mind) a bad motor and thermostat/thermistor. I browsed various appliance forums and saw that this particular brand of dryers has problems with the main control board failing. I did not get the various error codes that other dryers show on the display, just blinking lights.

I decided to google the corresponding number of the control board and I got it from appliancepartspros. It was the 134523200 part. I ordered it and it arrived the next day via UPS!

Installation was time consuming but not too bad. I looked at the instructions on how to remove the control board on [...]. You have to join the appliance junk website and search for the 5995456869 Frigidaire Affinity Dryer Service Manual. It took me about 3 hours to do it. I was taking photos and since it was my first time doing it, I wanted to be extra careful. It should take you anywhere from 45 minutes to 3 hours depending on your level of expertise/confidence level and so on and so forth. I also cleaned the lint off the dryer and off the vent, which increased my completion time. I would urge you to do the same and clean the insides of the dryer with swiffer dusters. You never know Maybe the dust affects the electronics, who knows?

I took step by step pictures and I have posted them on google pictures. Check on my profile, Eric Ilovegreatdeals (iluvgr8tdeals@gmail.com) and see the entire set of pictures which will certainly ease the removal and installation process. Its not that difficult. 5/10 difficulty! Good luck. The dryer is now running well and drying well for 2 weeks so far (fingers crossed!), cannot complain!
