Checked the vent, that was clear. Replaced the coils after testing per the info here, did not work. Gotta be honest the cost of the flame sensor, high limit and igniter were so fair I ordered all 3 and the dryer is running great. I want to say the ignitor was probably the problem but since I did not want to put them in 1 at a time to eliminate what the problem was I cannot be sure. Great prices the only reason they took 4 days to get here I believe was that I ordered them on a Saturday, other than that I will use this site all the time. One more thing, in the meantime my LG FRIG stopped sending water and filling the ice maker. I also ordered that part and was online in 2 days. Thanks.
