Yes, you probably can. Plus, Dimplex should be made aware of this. Contact Dimplex Technical Service 888-346-7539, Monday -Friday, 8a -4:30p ET. Have the model number, serial number and proof of purchase, handy when you call.

Hope this helps you get the parts you need.

Not an unusual problem with any electric fireplace heater. I suspect the overheat circuit has shut the heating element down. Or the element has burned up (that's not unusual either).

In any event, turn the fireplace OFF and unplug it. Wait 30 minutes before plugging it back in. During that time, the overheat circuit may reset itself. If that fails to solve the problem call The Technical Service Dept of Dimplex USA at 888-346-7539, Monday - Friday, 8:00 a.m. - 4:30 p.m. EST. If it ends up needing parts, you can order them at that time.

Have the Model # and Serial # of the fireplace, handy. As you will need to provide that information to them, as well as the date of purchase.

It probably overheated and the overheat module shut the heater down. It may reset itself once it cools down. Or the heating element has burned out. There are a host of issues with these electric fireplaces (not just Dimplex). They are sold as a decorative, supplemental heat source, but in fact, if you get more than a years use out of it without a problem, you're probably the exception. The heaters just aren't meant to run for a long period of time. It's like turning on a blow drier and letting it run for an hour. Nine times out of ten the blower driver will overheat and burn out.

I really wish I had better news for you (I answer this type of question at least 5 to 6 times a week), but I don't.

The only good news would be, if it's still under warranty (one year), have your Proof of Purchase and contact Dimplex USA. Technical Service: 1- 888-346-7539. Customer Service: 800-668-6663

This is a constant problem for ALL electric fireplaces with heaters. Either the Owners Manual fails to the manufacturer not telling you that the heating elements need routine cleaning, because they are sucking in household air to heat it and send it back out, So whatever is float in your household air (dust, lint & pet hair) near the floor goes into it, clogs it up and causes the heating element to overheat and fail. Or customers who have purchased these units don't read the Owners Manual.

These units, no matter who the manufacturer is were not designed to heat for long periods of time. In fact the heater element doesn't produce much more heat that a blow drier on high heat.

The heater and the blower and are in the lower compartment of the firebox. If you can access it, you can clean it with a shop vac and a brush attachment on the end of the hose. Be sure to unplug the fireplace from the wall outlet before attempting this. If cleaning it doesn't help, the blower motor will have to be replaced. You can order one from Dimplex USA.

This is an on going problem with electric fireplace/stove type heaters of all types. Not just Dimplex.
They are not designed to run for long periods of time and the heat output is not much more than a blower dryer. In any event, they take in cool air, heat it and send it back out. Over time, the heating element becomes clogged with dust, lint and/or pet air. So, they have to work harder to produce a sufficient amount of heat. Cleaning the heating element with a vacuum that has a hose and brush attachment may help. The heating element and blower are under the stove. See your Owners Manual on how to access it. Be sure to unplug the stove before trying to service/clean it.

If you no longer have your Owners Manual go to the Dimplex home page and click on the Help tab. You should be able to download the Owners Manual for your model fireplace there in a pdf format. Also look for a Trouble Shooting tab.

Heater keeps turning off and on every few seconds

The heater will not work if either the thermostat or blower are not working. (or the heater element is bad). Most of the time with these electric heaters, it's the thermostat.
