Does not always heat - LG DLG5932W Gas Dryer

Try disconnecting the power to it for 10 minutes to reset it. If that doesn't fix it, a new one is £63. The other possibility is that the floor heating wiring to the thermostat is incorrect.

Has this always been this way? When the emergency heat is on the outside unit shouldn't run. When in normal heat, no emergency heat, the outside unit should be running unless the temperature is below the balance point ( usually around 35 degrees). If this has always been this way and the outside temperature is above 40 degrees you might have your 1st stage and 2nd stage wires switched.

[Always disconnect the dryer from any power source before checking.] Dryer heating circuits have several parts in the series circuit that must all work (kind of like a string of Christmas tree lights) so you'll want to check each one in that series. These likely include the motor switch, timer switch, temperature selector switch, temperature controls/thermostats (usually three of these) and all connecting wiring plus the heating element. Of course, one should always make certain the dryer is receiving 220 volts power supply from the wall outlet before starting to troubleshoot the dryer. Most dryers operate with 110 volts, only using the 220 volts for the heater circuit. A dryer getting only 110 volts could run, but not heat. This doesn't happen often, but is always worth checking.

thermostat

need to have the freon checked. keep an eye out for places that offer a free a/c check

what type of system is it, if it's it Rheem the o/b needs to be set for B, if not check the freon charge, or thermostat, there will be a point where the aux. heat comes on when you turn it up, poss. only 4 degrees, is it a mercury stat or digital ?

the moisture sensor is probably bad

On the unit outside there is a button that says "push man. pull auto" if it is set to push man then the fan will go constantly.

I am assuming this is an electric dryer.

1) Thermostat may have failed.
2) Element may have broken at one point and shorted to ground.

Please reply your specific model number and I can help further.
