Turbo chef Door Hinge

[fixbear]

I have to ask why it need lubrication. They are built to be dry due to the heat of a oven. If it has gotten rusty and is binding, Then is was stored in a moist area. But if you have a problem with the door closing, Then more likely the door is out of adjustment. A graphite lube would probably last the best.

If you do not have access to a RF meter to test the door for leaks, Do not attempt a adjustment. Microwaves are very dangerous.

What model oven do you have?

Really appreciate for your reply. I am a student and am taking online classes for turbo chef. I have an old oven model number NGC-1070. I am practicing on it, but the oven door is very hard to open and close. I had removed and cleaned the hinge, and it is working smoothly. I also saw hard lubricant on the hinge while I was removing it. So my question is, that do I need high temp lubricant and what kind according to the model. In this case will the graphite lube work or please suggest.

My first inclination was advise a graphite-based lubricant used for burner valves:

Graphite Stop Cock Grease

That’s obviously made for a specific purpose. FWIW: there aren’t really any lubricants which can withstand 500°F for very long

I know that their hinges get hard to open and even get squeaky. Our newest BULLET ovens got to doing that after less than a year’s use. However, I haven’t yet opened them up to apply any lubrication.

I’ve seen that their hinges come with some type of brown-ish grease. Perhaps you should call TurboChef tech support and ask them.

Now we are getting somewhere. There are not many greases that are brown. So we are probably looking at a vegetable base Lithium thickened NIGI 2 grease. Does it get waxy and crumble when old? Otherwise it could be a Urea base synthetic. Doubt it due to the cost and special packaging in THC tubes. Fifty bucks for a 2.5 oz tube. Both are 350 F working temp. But vast differences in melting temp. I doubt the hinge area will get above that.

If you saw a white type of paste on the hinge, it was probably a food grade lithium made by Lubriplate. You never told us if you have any corrosion or just dry grease. To free it up I would either get a squeeze bottle of Lock-Ease from a automotive supply or mix powered graphite with a little alcohol and light oil to squirt into the pins. But most problems with the Turbo-Chef’s are alignment. It’s a bit tricky to get right.

Finding powered graphite is easy from any hobbie shop or Boy Scout center. Think Pine-Wood derby wheels.
