Question about Presto HeatDish Compact Heater

Presto Heatdish noise.

The heatdish makes a constant noise like it had been bumped when it was working OK. I had it turned on and left for a few hours and when i returned the bumped warning was going off. It is now continuous.

    Remove 115 VAC [power cord.

    I just fixed mine. I had a broken wire inside the wiring box. My unit is a few years old and there was evidence of a loose connection that finally arced through a lug connection and it fell off. I had the same issue as you. Now the unit is quieter that it has ever been. I think it came from the factory with one of the wires not connected securely. I removed four screws from the 4 X 6 inch cover that give access to all the wiring and warning switches. I also found a switch mounting bracket that was loose, so check it over good. I have pictures of all my effort if you desire them.

I know the metal dish has to be dust free, clean. Beyond that you may want to call their customer service number 800-877-0441 for more help.

When i turn on my heater after a few minutes it will make a long buzzing sound

1. Check for loose connections at the heater coil terminals area. If everything's alright, one of your heating
elements is about to give up, and it may need to be replaced.
2. You may also check the other components, since you will be opening the HeatDish Compact Heater.
Hope this will help you.

Heatdish turns on and off too quickly

the sensor in the top of the dish has gone bad and needs to be replaced, or bipassed. if you want to bypass the switch then take the back off and remove the two wires going to the round silver plug looking item at the top and wire them together.
problem solved.

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
