Kenmore 80 Series Model #110.74842400 Series MR5112733
Product with problem: Kenmore 80 Series Model #110.74842400 Series MR5112733 Front loading dryer.
Problem: No heat, but cold air with force is present when the dryer tumbles.
I've been reading replies to other people's problems regarding no heat in their dryer. I have the same problem. I cleaned the air duct, which had some significant amount of lint built up right at the base connection of the duct.
I wanted to see if I can service the dryer myself. I build computers for a living and do light electrical work, so I figured I would give this a shot before calling for servicing.
I kindly thank anyone for information in advance. Regards, -dc

Re: Kenmore 80 Series Model #110.74842400 Series...
There's a few things on this dryer that can stop it
from heating. 1st thing your going to need is an ohm meter, your testing simply for continuity. The main items that cause no heat at all on this gas dryer is the igniter on the gas valve, the thermal fuse located on the blower wheel housing the thermal cut out located on the burner box or the flame sensor on the burner funnel and lastly the coils on the gas valve. the sequence is from most too least common. Of course unplug it and shut the gas off.

Yes, but there are several thermal limiters, they should reset when the unit cools, so likely that is not what is happening.... Forcefully turn the breaker FULLY off, and then back on, and test again...
The thermal limiters are located along the air flow path, typically downstream of your burner, the purpose is to prevent overheating and fire. These limiters stop the HEATING element and not the drum motor...
Kenmore 80 Series of dryers are consumer grade dryers for home use. As
with most home appliances, the Kenmore 80 series dryers will
occasionally not work as intended. If a problem occurs with your dryer,
however, you do not necessarily need it serviced by a technician. You
can attempt to troubleshoot and fix any problems with your dryer before
contacting a technician.
Kenmore 80 Series dryers may not run for several reasons. First, make
sure that the power cord is plugged into a working power outlet. You
may need to plug a different device into the outlet to check that it is
receiving power. If the second device does not run on the power outlet,
you may have blown a fuse or tripped a circuit breaker. Check your fuse
box or circuit breaker box and make the change as needed. Next, make sure that the dryer door is fully shut. The dryer will not run with the door ajar. Finally,
check that the "Start" button was fully pressed and that a cycle was
chosen on the machine. If you do not choose a cycle for the dryer, it
will not run.
If your Kenmore 80 Series dryer does not heat up during use, check that
a heat cycle has been chosen for the load. There are several different
dryer cycles you can choose, some of which do not use heat. Make sure
that you have chosen a heated cycle. As
above, check that you have not blown a fuse or tripped a circuit
breaker. The dryer may use more than one fuse or breaker: one is used
to power the drum, and the other for the heating element. Make sure
that both fuses or breakers are in working order.
There may be times when Kenmore Series 80 dryers do not fully dry your
clothes. When this occurs, check the lint screen and clear out any
lint. The air may not flow as well if the lint screen is clogged. Next,
check to see if the exhaust vent is clogged. Lint and other particles
may clog the exhaust vent over time, restricting air flow and making it
more difficult to dry your clothes. To check the vent, run the dryer
and hold your hand under the vent. If you do not feel any air flow,
clean or replace the vent. If you used cold water to rinse the
clothes it may take longer than normal to dry. The same is true if the
load of laundry is very wet or is filled with items that are very
absorbent. Finally, check the load size. The more clothes in the
load the longer it will take to dry. If you want to reduce drying time,
separate the clothes into piles of light and heavy items and dry them

bad heater box fuse,get the model number from inside the dryer door,and go to your local appliance parts store and give them the number and they will get you a thermal fuse kit,remove the back of dryer and you will see the heater box on the right side
check outside drye vent where it goes through the wall they clog up with lint sometimes and force the escaping warm air to back up which causes sensor to give wrong reading if this is clogged just clear it till you feel the air coming through also check vent at bottom of dryer disconnect flex pipe and check for clogs there as well ..and always clear lint trap after every load
most of these dryers have a little plastic plug on the front, left side. pop that plug out and look inside after turning it on. you should see a red glow. if not, then your ignitor has broken. if you see a glow, then the problem is probably one of the two little coils on the gas valve. these coils will sense if there is something to light the gas [the red glow] and open the valve - if the coils are bad, they won't open the valve
