Rheostat vs. Thermostat Temperature Control

Will it work for me to plug my parabolic, infrared heater into a properly rated rheostat?

What I want is my heater to run continually at 1/2 power, 1/3 power, or whatever power feels comfortable. And I really don't like how normal thermostats turns on and off repetitively. On a regular heater, on/off is fine. But, for this I would like continual, comfortable, regulated heat.

To me it seems like it would work fine. I think that's how standard electric stove tops are regulated.

Re: 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 and known as speed controllers. I use one for a large air fan in my garage.

Why does the air conditioner comes on when turned its turned off at the thermostat?

Sounds like the internal thermostat is stuck causing the unit to think that it is not cold.

If you would like to tackle it yourself it is usually a part of the Expansion valve, witch will require opening the system. I suggest a service professional as Freon is hazardous, and being wrong is expensive.

It could just be that the rheostat on he control knob is going bad BUT that wouldn't cause Ice to form on the Unit.

Model dlb503 works when set at half heat , but when set at full heat it cuts off after a few minutes, even when room is cold

i've experienced the rheostat failing in other brands of electric fireplaces. the rheostat is the component that varies the voltage, thus the power. some are replaceable by generics available at big box or hardware stores. if this is your problem, it will eventually also kick off while on low.

The fan cuts off almost immediately after being

You could have a bad Heat sensing switch...or the wiring itself could be a bad connection........UNPLUG the heater first.....follow the wires coming from the fan and they will lead to the switcvh that brings the fan on...ensure the connections look ok......If they are fine install a "jumper" wire across the 2 terminals and plug the unit back in the fan should run continuously....then you know the switch is no good....if the wires go to a Rheostat (adjustable speed control) ensure that the dial is on....becareful the jumper wire doesn't touch anything...and test it will be able to tell if the fan is may also be able to simply marette the wires going to the switch together which is the same as a jumper wire...if you're unfamiliar with Electrical or anything I'm saying I suggest you call a Qualified Technician

Thermostat for baseboard heaters in series

The heaters need to be wired in parallel so they all receive the same voltage. If wired in series the first heater will receive proper voltage and the next heater will receive reduced voltage (Voltage Drop across first heater) and so on (Ohm's Law). You may want to have an electrician help you so you don't get electrocuted or burn up your heaters or your house. Hope this helps!

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
