Switches itself off intermittently Dimplex Danville optimyst

Do you mean Dimplex OptiMyst? All question need full 'make model (what it is)' please.
I moved the question from Cars and Trucks category.

This is very new technology and proprietary to Dimplex as this is a patented system. It is entirely likely that everything needs to be functioning. Contact Support and claim on the warranty. It can't be very old?

Check amount of beep and compare it with unit troubleshooting chart.

Take it out and see if the fan wil turn by hand. It may have somethng obstructing it. The clicking is the motor overload. It wil burn out if it continues to keep clicking.

When it is switched off try spraying WD40 around end of spindles. Try heater again after about an hour.

I had the same problem. It turned out to be the lamp holders themselves which were the problem. Just take out the single screw just in front of the lamp holder assembly and the lamp holder unit comes out. Remove the main lamp holder assembly and turn it over. You will see the four lamp holder wires all go to two main terminals with a positive and negative connector on each. You need to undo the nuts holding the main supply cables and lamp holder wires and remove the cables noting where they came from for easy replacement. If you cut off the wire on the defective units and unscrew the two retaining screws holding each lamp holder they can be removed. You can order on line replacement holders from Amazon and with a little bit of simple soldering and using new wire connectors for the end connectors on the new lamp holder wires can be easily fitted. I have two of these fires and both have had the same fault after about 12 months use, obviously a fault with the holders as they dont last that long and need replaced.

Before call Dimplex Technical Service (888-346-7539) have your customer turn the Master ON/OFF Switch to OFF. Unplug the fireplace for 12 - 15 minutes. Once plugged back in, have them turn the Master ON/OFF Switch to On and then turn ON each function of the fireplace one at a time. If everything is performing as it should, the unit reset itself. However, if this becomes a recurring problem, they should contact Dimplex Technical Service.

Hope this helps you solve the problem for them.

Ar e you sure that the receptacle your have it plugged into is working? If it is, you can try this. It usually works. Turn the Master On/Off Switch to OFF. Unplug the unit and leave unplugged to 12 - 15 minutes. Plug the unit back in and turn the Master On/Off Switch to ON. Then, turn each individual function one at a time. If they ail function as they should, the unit has reset itself.

If it doesn't work, then you'll have to wait until Monday to contact Dimplex OR you could contact the retailer you purchased it from and have them replace it immediately. That is, unless you purchased it online. Then, it would be better to wait until Monday and contact Dimplex. Be sure you have your Model Number and Proof of Purchase, when you contact them. In case you don't have it, their Technical Support number is 888-346-7539.

Hope this helps you solve the problem.

Maryanne, the first thing to try is turning the Master ON/OFF switch to OFF. Unplug the unit and allow it to remain unplugged for 10 - 12 minutes. Generally, that's enough time for the unit to reset itself. Plug the unit back in and turn on the Mater On/OFF switch and then proceed as you normally do.

If that solves the problem great! If it becomes a recurring problem, turn the fireplace off, unplug it and call Dimplex USA Technical Service 888-346-7539.

Hope this helps to solve your problem. Please let me know.

I have the same problem with 3 of the 5 EPX1000s I have fitted in my flat, although mine don't even warm up. They just immediately turn themselves off. My only conclusion is that they are rubbish. Specifically, the so-called overheat protection doesn't work. Avoid.
