I've read all the posts on my particular dryer on here, and have gotten lots of good info, but I don't know if my particular issue has been covered. I recently replaced the cord on the LG DLE7177WM and I noticed, even though it was installed with a 4 wire cord, it was wired like a 3 wire cord, with the neutral inside the dryer being tied to the ground. I installed the new cord with both neutrals going to the white, neutral terminal. Everything ran fine for a few loads and now whenever I put a load in to dry, after setting to even high heat timed dry, the display flashes "DRY" and the "cooling" displays solid. I've scrubbed the sensors on the inside of the lint trap, i've cleared all the blockages and actually shortened up the vent pipe between the dryer and the wall. The dryer vents to the wall makes a 90* turn and has about a 5 foot run to the outside. I took the vent pipe off completely and it's blowing just fine but it's cool air, not even warm. I'm wondering if i need to start taking things apart and testing parts. Could the cord thing have screwed me up? If i put it back with the dryer's neutral tying to the ground, would that mess anything up? Could someone explain to me how it worked with a 4 wire cord wired like a 3 wire? What am I to do here?
