SOURCE: Heat Disk Temperature Control (Rheostat) doesn't work properly

The switch inside is a thin piece of metal that flexes as it gets warmer / colder towards a pin that conducts power. This pin is rotated towards and away from the thin piece of metal as you rotate the dial counter clockwise / clockwise. The thin piece of metal glows when in use as resistance to electricity running through it causes it to heat up. You have seen this through the vent slats under the dial on the back of the unit. The resistance the thin piece of metal provides causes the electricity usage to be lower and the reason the unit has an 800w to 1500w power rating. The thin piece of metal is failing. You can have the heater FULL power but that is blowing lots of $$ in electric and you may not need all that heat. In the end the thin piece of metal will FAIL so the heater will no longer turn on at any setting. You can bypass the switch since the heating element and everything else is still in good working order and have a heater that works on 'high' all the time when that happens. You CANNOT order just a new switch, which would take anyone less than 5 minutes install. I thought the switch design was ingenious but poor quality metal even though it is a fraction of an oz in weight (since it is so small they SHOULD HAVE used better quality metal, it would have cost next to nothing extra) is most likely the culprit here. It is sad that the Presto Heatdish has to go to the landfill due to such a simple materials error. You will see how to bypass the switch though so it is on 'full and full time'. Maybe purchase a high wattage timer for it so you can set it to turn on in the evenings and mornings for a specified amount of time? Some good timers are around $7. Stan Horstman

SOURCE: Rheostat vs. Thermostat Temperature Control

yes, it should work. Just ensure your rheostat will handle up to 1500 watts at reasonable settings. A better approach is a 1500 watt pulse-width modulator circuit that draws little power itself. these are available where power tools are sold (like harborfreight.com and known as speed controllers. I use one for a large air fan in my garage.

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

SOURCE: Presto Heat Dish buzzer

for those of you that want to void your warranty or just dont care there is a fix for the buzzer problem.
If you take the three screwws in the back and the one in the top next to the heat selector switch the steel dish portion will come away from the dish back. located on the bottem of the back inside panel there is a small disk looking tilt switch that has one red wire on one end and on the other a white and two black wires. remove this component and all wires from it. take all the wires from it and remove the ends exposing solid wire. for this modification you will need a philips driver wire stripper and cutter and one medium size wire nut available at almost any hardware store. take all the loose wires and wrap them together and place the wire nut on them. be sure to tuck the wire someplace away from the dish portion when going back together. put the unit back together and plug it in and "presto" you have no anoying buzzer anymore and the heater wont go on and off like it used to. this seems to be a comen problem due to lack of insulation and poor design on heatdishes part. hope this solved your problem

SOURCE: Cleaning the dish on my Presto space heater.

I pried the upper rim with needle nosed pliers --,just enough to get the grid off. After cleaning with Mister Bubbles, I popped the grid back in and bent the rim back down. I then took a hammer and
smoothed the rough edges. Looks almost like new!!

RE: Presto Heat Dish buzzer going off


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
If you have further questions, please let me know. Or call us at 1-800-877-0441 Monday through Friday 8:00 a.m. to 4:30 p.m. Central Time.

Is there a way to disconnect the alarm on my Presto parabolic heater? It comes on and works for about 5 minutes and then the alarm goes off. We are adults - no children around.
