Jeff Matthews Posted July 28, 2020 Share Posted July 28, 2020 Kenmore 700 series electric dryer. Model 110.67751600 (ht Carl). It heats but takes 2 long cycles to dry towels or jeans. I'm pretty decedent at replacing components, but I can't figure this one out. The dryer heats, so the coil is good. I replaced a burnt coil a while back. Prior to the coil failing, I had the same slow drying problem. I checked the lint filter, the blower and the exhaust. No blockage. I checked the thermostats for continuity. All have continuity. I heard of a thermistor, but don't readily see much about it. I see videos on how to check them, but if the fact that the dryer produces "some" heat means it is not defective, then I won't bother with it. Any thoughts?

By "exhaust", do you mean the exhaust from the dryer itself, or do you mean the exhaust leading all the way out of the house? I've had the duct leading to the outside world get clogged, resulting in this kind of problem. 1 Quote Link to comment Share on other sites More sharing options...

Is the spin cycle on the washer getting all the water out?Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Jeff Matthews Posted July 28, 2020 Author Share Posted July 28, 2020 The exhaust all the way out (through the roof) is clean. The washer's spin cycle is good. Quote Link to comment Share on other sites More sharing options...

avguytx Posted July 28, 2020 Share Posted July 28, 2020 I'm assuming yours is still spinning the entire cycle when it's drying right? We had a Whirlpool fail at 1.5 years of age and the Lowes warranty deal bought us a new one as the repair guys claimed it was beyond economical repair. On ours, the motor would get hot and a protection circuit would shut off the motor but keep counting down. So, it ran for 8 minutes, shut off for 14, ran for 8 minutes, shut off for 14, etc. Quote Link to comment Share on other sites More sharing options...
Jeff Matthews Posted July 28, 2020 Author Share Posted July 28, 2020 The old coil is gone. The new coil provides heat. The dryer operates (tumbles) for the full length of the cycle. We're seemingly running out of options, I know... Quote Link to comment Share on other sites More sharing options...
babadono Posted July 28, 2020 Share Posted July 28, 2020 How hot is hot? Are you getting full 220v to the heating coil? (all electric dryers are 220 I assume). Quote Link to comment Share on other sites More sharing options...

And there is a relay or contactor somewhere in the circuit also I would assume. If you have a way to check the voltage at the heating coil that's where i would start @Jeff Matthews Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted July 28, 2020 Share Posted July 28, 2020 The techs at the forum I linked above are da bomb. Doesn't take them long to figure things out. Check to see if one leg of the dryer breaker is tripped. 2 Quote Link to comment Share on other sites More sharing options...
JJkizak Posted July 28, 2020 Share Posted July 28, 2020 Or if you have fuses check the fuses. (Yes some old people's houses have these things called fuses and if one burns out you only have one leg hot) JJK 1 Quote Link to comment Share on other sites More sharing options...
oldtimer Posted July 28, 2020 Share Posted July 28, 2020 Hang jeans to dry. Fix your dryer for sheets and towels. Hang the rest. Your clothes will last decades that way. Quote Link to comment Share on other sites More sharing options...

JJkizak Posted July 28, 2020 Share Posted July 28, 2020 And hopefully you did not hook up the new heater wrong. Some of these foreign machines do things in reverse. JJK Quote Link to comment Share on other sites More sharing options...
