Hello, i'va a kenmore gas drier model 75818,the
next time send the full model number,starts with 110. or similar,i would change out the gas coils located on top of gas valve, do one at a time and look for a metal spacer that needs to stay on post,sometime it slides off when you remove the coil,only on one of the coils,also if you haven't cleaned out the dryer it would be a good idea to do so, unplug dryer,if lint filter is on top remove the filter and the two screws in front of filter,remove the vent line if it's a long run blow it out with a leaf blower or shop vac but leaf blower works better,take off back wall and take out the four screws that hold the duct in that the filter slides into,clean out the duct,put it back together except for the two screws on top,now pop the top and remove the front panel and vac out the inside,if you have a shop vac blow out the dryer motor and all,if filter is inside remove the bottom panel take out the lint filter and remove the duct the filter slides into and clean it out,if you have a shop vac blow the lint from the back to the front so you don't have to pull the drum,blow out the vent line,you should do this once a year you have an open flame in there and you don't need a fire,your dryer will run better and last longer
