The hardest part of cleaning the dish is that you can't get your hand inside the cage surrounding the dish. What I did was to use a wire cutter to snip enough pieces of the cage off so that I could get access to the dish. If you do it carefully, it looks as if it was intended and doesn't prevent the cage from working. If you think of the cage/dish as a clock, I cut all the strips between 9 and 11, and 1 and 3. Easy to clean the dish afterwards.
That might not solve the buzzing problem, though. It didn't solve it for me.

It all depends on the how much dust has accumulated on inside of the dish.
Try to use the Swiffer first before mechanically altering any part. Slide the duster in through the grate, and move it around. Pull it out and repeat on the other area. You'll just have to do this around 3 times. If heavy clean is necessary, then you might have to resort to bending the lip of the dish to separate the grate off from the dish.
IMPORTANT: make sure the unit is unplugged and cool down before attempting any of these cleaning methods.
I almost threw my heater out! I cleaned this morning with Window Cleaner and it works just fine now. It was just dust. I cleaned the round metal area not the coils.
Hope this helps.
Emailed Presto about replacing the buzzer and here is the answer I got:
There
is no such part.
Buzzer sounds when heater:
- is tipped
- rests uneven on floor
- is too close to furniture or wall
- has too much dust on parabolic dish
The most common reason is that the parabolic dish is dusty.
To clean the heater:
1. Unplug the heater and clean it when it is cool
2. Spray a cloth with an all-purpose cleaner such as 409
3. Wrap the cloth around a long handle such as a wooden spoon
4. Wipe between the grate from the outer edge to the center

This was the answer from Presto as I had the same problem. Cleaned it with window cleaner and a wooden spoon and paper towels and now it works great!

'tdulany's remedy for cleaning the dish on the Presto Heat Dish probably works well, but how do you get past the grill covering the dish in order to clean it?

We have one in our office where our entry is pretty close to teh main door. It used to buzz all the time after being on for maybe 10 minutes. One day I got sick of it and took a cloth and some windex and cleaned the reflecting dish, and that actually stopped it
This heater must be flat on the floor or it will buzz, and the metal dish must be clean or it will transfer heat to the safety device. If this does not solve the problem call customer service at 800-877-0441.
