We had it delivered and then had to have it converted to propane, then after the technician finished it then went to go through everything we got a code saying DOOR,  so with that happening you couldn't use the oven.  So our technician said we should  call L.G. to find out the problem in which it was the door switch.  L.G. sent out there technician and repaired it. So far there is no problems. I would like to think there would be a better Quality Control.  .
