Whirlpool let7848dqo no heat

ELECTRIC Dryer no heat or little heat, or shuts down to fast:

Check your venting and lint basket. Check blower for lint build up and blower wheel obstruction., test by trying to turn the wheel manually by hand (should be easy) May have to remove cabinet or front/back plate to get to it)

Next check the heating element itself with a meter for continuity OHMS CLOSED CIRCUIT. If not its defective.

Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage. 220 because if u only get half or 110 volts you will be able to run the machine which uses only 110 to run motor but not the heater which uses a full 220,

Check the thermal cut off, the cycling and the hi limit thermostats.
For continuity or OHMS. If no ohms or resistance they need replacement.

Lastly check your moister sensor. ( located inside the dryer door usually) Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.
A failed moisture sensor will affect the dryer run time in the automatic moisture sensing cycle but it will not affect the heating of the dryer or the timed cycle.

The thermal cut-off has blown open due to the high-limit thermostat failure to cycle off in order to regulate the heating element temperature as the noticed extreme dryer temperature indicates. These two components are wired in series with the heating element as a safety measure to cut power to the element should the dryer temperature go extremely high like your case.

Disconnect power then make sure the lint filter is clear, the vent system is not restricted, and the inside of the cabinet is clean. A vacuum cleaner may be used to extract lint built up inside the dryer cabinet particularly the bottom. Replacing both the thermal cut-off and the high-limit thermostat is a must but only after the all areas mentioned are cleaned.

I'd like you to try something easy. Set the dryer to Air Fluff and see if the dryer still puts
out Heat let it run for about 2 full minutes If you dryer is still putting out Heat get back to me

sounds like a heat sensor to me. Sorry but you will have to get it tested or buy both sensors on your heat element. look in the dryer as its running... Does the heat coil turn orange in the dark???? If it doesnt you will have to replace the heating element.. (should be about 75 bucks)

You have to let us know what it is doing, and what it is not doing. Is the new heating element getting red hot? Is the motor running? Did you clean the face of the flame sensor, a little gizmo attached to the firebox?

look for an "open" thermostat either on the heater can, or a thermal fuse has gone bad, probably shorted out when the element broke.
