Question about DeLonghi EWO507 Oil Filled Radiator Heater

1 Answer

Popping and spitting sounds

My radiatior heater has recently stopped heating as well as normal, and just a few minuites ago started having popping and spitting sounds coming from inside of it. The sounds are similer to the sound of frying something frozen. Is this a problem that we should unplug it? Should we dispose of it? I think that there's no warranty, or if there was, it's expired, though we only got it three months ago. We have had a handful of power outages. The heater has been tripping the breaker, if we use anything else on the same circut. (IE; Microwave, coffee maker, other heater) Might this have caused a problem?

Re: Popping and spitting sounds

Theres a loose wire somewhere inside. Have someone with a little experience open it and look for the loose connection. Guaranteed to work!

I have a master mh-135t- kfa runs and burns but the flame is popping.

This could be an air-fuel mixture problem. Make sure the air-fuel mixture channel is clear and fuel source is normal. If it has set for a long time without using it, a spider could build a web in there and that's about all it would take to cause a problem. I don't know what the popping sounds like but popping is usually due to the flame going out at some point along the line and then re-igniting suddenly.

My delonghi oil heater is very noisy whilst hearing up

This is perfectly normal as the oil gets thicker the colder it is and over a period of time it's viscosity changes.Once the temperature gets above a certain point the oil will melt and the heat will flow through more freely so the popping/crackling stops.

The heater began making a popping sound and sparking. Now it won't heat at all. Is there a replacable heating element?

It may be, but I'm not sure. However, you can contact Delonghi USA and speak with one of the Customer Service Reps @ 800-322-3848, Monday - Friday 8a - 5p EST.

Hope this helps to solve your problem.

My electric baseboard heaters make a pinging sound which drives me nuts when I am trying to sleep! Any suggestions other than changing the unit? Thanks

Electric baseboard heaters heat by radiant heat. This mean the heater is heating the metal of the heater first which causes expansion of the metal. This will cause popping metal sounds becouse it is heating up. When it kicks off, by the thermostat, it starts to cool which causes contraction of metal. This will also cause noise. Most all base board heaters I have installed and worked on does this. Sorry there is little to nothing you can do. :)

Very loud wall heater (bang!!) heat up and cool down.

cozy heat exchangers do tend to make a lil more noise than avg. if its popping before the blower comes on its proubly the heat exchanger expanding. you would have to watch the exchanger while it was heating to see exactly what is causing the noise. but as a renter you should try reporting it to the landlord first and try to get a tech there before digging yourself

Does it sound like oil bubbles? Sometimes when an oil heater is heating up you can hear the pop sound of the oil heating.

Connector for power cord overheats and shorts. Bottom safety screw can be undone using the bacj end of a jig saw blade.
Replace wire connectors with different wire connectors - wire nuts etc.
