electrical interference by Peltier cooling devices

This question is regarding the possilbe electrical interference that is generated by peltier/thermoelectric type cooling devices (including but not limited to computer CPU cooling).

Recently I purchased a small peltier dehumidifier to replace the NOISY regular dehumidier that I am using.

Upon hooking up this device it ran fine and was almost completely silent. However, when I went downstairs, I noticed that my TV picture was distorted/snow. So I went back and turn the dehumidifier off and the TV picture cleared up. I repeated this several times to make sure it was the cause. It was.

My question is is it a common occurance for these peltier type devices to cause electrical interference in other adjacent electrical devices or was this just a defect in the device I purchased ?

Thanks.
 
I have recently been reading up on peltier cooling devices and from what I have been reading in order to avoids such interference you must first of all follow all the direction exactly as stated!
If you did that then I will tell you that what you payfor is what you get along with possibly electrical interference.....
I really didn`t have the time to read on about a possible solution but I would have to hypothesize==guess that you could probably get some sort of a filter to filter out the electrical interference!!

Good Luck!!🙂

 
The TEC is a 12v- 24v DC device with no moving parts . A good quality Power supply is not a problem . why your getting feed back . Could relate or must relate to the PS.

Turtle you totally misread the issue or just don`t get it.....
This has nothing to do with "moving parts"!!

This has to do with interference caused by any number of things...electrical in nature!!
 
The thermocouple joints (dissimilar metals) could radiate if done poorly, but more likely the power supply for the dehu.
