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 or has a short if its grounding out? Which in turns causes blown fuses or thermostats or
overheating.

The heating elements are located inside the heater ducts. If you think a heating element is faulty, test it with avolt-ohm-multimeter (VOM)set to the RX1 scale. Disconnect the leads from the power terminals and clip one probe of the VOM to each terminal. The meter should read about 12 ohms. If the reading is higher ohms, the heater is faulty and should be replaced. Replace a faulty heater with a new one of the same type and electrical rating. A heater connected to a 115-volt line usually has an 8.4-ohm resistance; a heater connected to a 220-volt line usually has 11 ohms resistance.


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.

In some dryer's the control panel relies on a thermistor rather than a CYCLING thermostat to regulate the drum's air temperature by monitoring the component's resistance changes; resistance goes down as temperature increases and up when temperature decreases. Once the drum's air temperature reaches a certain level required to dry clothes, the control panel shuts off the heater. The panel will turn the heater on again and begin another heating cycle when the thermistor indicates that more heat is needed to keep the air temperature constant inside the drum

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. Which are reflected by the thermostats.

Replaced all parts for dryer because of no heat dryer runs drum turns had breaker and wiring going into dryer everything ok still no heat could wires be backwards going to replacement parts?


Electric dryers have as many as three thermal fuses. See if you might have missed one. One next to coils, one next to drum and one near the lint trap at air outlet. All three have different trip settings.

My temperature says HI. but my temp is not warm


The error code is HL, not hi
This is telling you the high limit switch is tripping(safety feature)
Lack of flow, corroded heat exchanger, bad high limit switch, bad thermal regulator.....
Take these steps to try and get it narrowed down.
With heater off
Locate the high limit switch, unplug the two wires connected to it, put a jumper wire in between those two wires. Turn on the heater, if it fires you need to wait till it heats all the way up. If if heats up with no fault in the cycle then most likely it's a bad high limit switch, if it continues to trip then thermal regulator, it may need both parts.
If it doesn't fire at all then you will probably need a professional

there are limit sensors around fire box.you need to remove front cover.if flames are coming out of fire box there's a restriction in air flow. on older furnace could be fan belt . air cond. coil could be pluged up are all the vents open and have good air flow?you check limits by pulling one wire and check with ohm meter.there normally closed and open when too hot.most limits around fire box don't reset them selves.on some draft inducers there's a limit if it is tripping then theres a vent problem.theres also a limit on the fire box (heat exchanger) that may or may not self reset.

Hello there :
There are severaol things that could cause this to happen
Things to check are :
- house fuse or breaker ( needs two of them ), heating element, burnt wire, thermostat(s), thermal fuse ( not all models ), motor heat switch, timer, selector switch, burnt power cord/plug.
I know that you have checked the thermal fuse so you dont have to worry about this.ok

Hope thatthis is very helpful

Best regards Michael

I shut off the gas to the unit and the power.i


No, that does not seem correct. If all you did was replace the heat exchanger, then tried to start it up, how could everything go wrong. Unless there was another issue with the heater. Not too many people change out the exchanger, unless corrosion has caused a leak there What you CAN try to do is reset the heater. To do this, turn off your heater first-at the toggle switch inside the right hand side door, then turn off the circuit breaker to the heater, wait about 5 to 10 minutes, then reverse the order. Circuit breaker then heater, if you have the digital display, you will see flashing codes, this is the computer resetting, then you should see the normal display. Try starting the heater again. If it still will not fire, let me know if you receive an error code. Also, check to see if the temp the heater is reading is close to that of the actual water temp.

Have you tried to bypass the hi limit switch or the thermal switch. It will work. If it works for a few times, then you will know the switch is bad. I did this on a friend's one time and it solved it. Only cost about 15 bucks. Godd luck and let me know how it turns out.
