Question about Presto HeatDish Compact Heater

1 Answer

My presto heat dish only puts out a little heat, even on the highest setting. Then other times it puts out full heat. But seems to be operating on the lesser heat more often. I have only used it one season. Any advise?

Check out some of my other posts regaurding rewiring the unit as this is most likely a burnt wire or bad contact at the selector switch.

Clean dish

'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?

Presto Heat Dish: footlight lens

The wattage of the replacement bulb should be 4 watts or less. Don't know the wattage of a C7. It is still safe to use. You could call Presto at 800.877.0441 or find a 4 watt bulb.

I bought a Presto Heat Dish at Costco (Calgary) and not even a year later the control switch's filament burned out. can you send a replacement switch or provide me with a local supplier so I can return the defective unit and repair it myself?

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

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

Presto Heat Dish w/footlight

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.

Presto Heat Dish

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.

Presto Heat Dish Blows Circuit

It sounds like the heater is drawing more amps than your fuse is capable of handling. look at the i.d. plate and see what the wattage is for the appliance.

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
