LG Dryer/Model dle7177wm/no heat

7 posts in this topic

I went out and looked at this dryer and replaced the thermostat as it was not heating , two weeks go by and now no heat again. Is there something i should be looking for that would cause this thermostat to blow ?

check for a venting problem, maybe clogged lint trap (dryer sheets can cause this condition).  Bad cycling thermostat can also cause this.  Maybe change it also if the vent is ok.  It can ohm out ok and still be intermittently bad.

for sure it would be good to eliminate it as a possibility.  I fought one for six months.  When I was there it worked fine.  One month or so later I get the call.  Thermal fuse.  After changing 3 of them and checking everything, even putting the vent tube in a bucket to make sure it wasn't restricting.  The vent went into the wall so I suspected it for a while.  Anyway as a last resort I changed the cycling thermostat and low a and behold, wah la, that was it.  If it was me that's what I'd do.  Good hunting!

Always replace the HIGH LIMIT THERMOSTAT whenever a Thermal Limiter has failed (per LG Service Bulletin)

As mentioned by the other sharp tech:) ...

 

*Verify* (don't assume) that the venting (in the home) is indeed clear.

 

Check the Lint Filter (waxy lint accumulation)

 

Though unlikely---check the Filter Housing plastic "screen" for accumulation/blocked (airflow to filter blocked)

 

During winter months---check the outside vent hood (not covered/buried under a snow drift)

 

Verify that the Door Seal is still attached to the door (not missing).
