LG Fridge-Freezer model no. GR-T632DVQ The upper freezer lights works. The lower fridge light stopped working. When tested the light bulb works and is NOT broken. There is a combination double switch that operates both fridge and freezer lights when each door pushes on a separate plunger. How do I replace this light switch?

You have a clogged defrost drain tube. best way is to thaw unit out. Your vents are being blocked so no air flow is pushed down.

heating element seems bad,,sometimes a easy fix

There are 2 or 3 things that would cause this. first make sure the condenser coils are not plugged with dust (vacumn or blow them out) next check to make sure the fan that cools these coils is running, (this is the most likely problem). if both of these check out ok then you would need to check to make sure your interior lights ar going off when the doors are closed as these will add extra heat and cause the center rails to run hot. last and most uncommon would be a freon system problem.  

fyi there is a hot gas freon line that runs in between the doors to prevent exterior sweating. when poor or no air flow problems for the condenser coil exist it causes this area to become hotter. 
One more thing. if you do determine that the condenser fan motor is bad you can put a normal house fan blowing on to the coil to help cool this area down until you can get the unit repaired. 
If you need any further assistance leave me a comment here and I'll gladly get back to you. Thanks Peyton

Find the drain tube in the back and check it for a frozen state. If it si,use a hair dryer to thaw it. If it does it again, you have a defrost problem

There are usually 3 or 4 locking tabs on the cover that just need to be pressed INDIVIDUALLY toward the bulb to release them and then carefully remove the cover. The ones with 3 tabs usually have and upper and lower tab then the thrid tab is on the side. Removed the upper and lower tabs by pressing inward to the bulb and then the cover will pivot out on the 3rd SIDE tab.

Thanks for using FixYa.
