Question about Air Conditioners

Open Question

We have a Dimplex "Oil Filled Column Radiator" Model OFC2411TI It has been turned off (and unplugged) all summer and now that we have turned it on, the Electronic Timer Operation panel does not light up. The neon at the top is glowing indicating the power is on, but even when the machine was turned on for 16 hours, no heat was produced. Thanks in anticipation ****

    Same ~ switched on and a dim light on the electronic timer but even hitting reset won't turn it on, there doesn't seem to be anyway to get the cover off to change the battery, does anyone know how to do this or override the electronic timer so the heater works manually?

SOURCE: Fujitsu Heat Pump - problems

I had the same problem. The heater did not work in heating mode. However it was OK in air-conditioning mode. The operation light and the timer light blink twice and then the operation light blinks for 5 times followed by few seconds non blinking, then the cycle repeats again. I have read on the internet that you better unplug the power cord and then plug it again so that the heater re-sets itself. My only problem was that my heater is directly plugged to the power with no visible plug. So I went to the main distribution board and put off the power for about 20 seconds for the whole home. HOORAY!! The heater worked after that.

You have not specified the make nor model. Five flashes can indicate a blocked drainpan and drainpipe which needs cleaning.

Try setting the Unit to run full out, set unit at 66* it maybe the lights flash to let you know the save ( power) is on ?. Otherwise look for the manual and troubleshooter page .

SOURCE: The operation and timer lights on my Fujitsu split

I have same problem like yours to my newly installed Fujitsu multi-split system (the first time use since system installed 1 week ago). I rang the electrician who did the installation; he said it must be the units themselves nothing to do with electricity.

Okay, then I rang Fujitsu and their local service agent. They suggested me to switch off C/B for an hour to reset the units. I followed the instruction but the indoor units still did not respond to remote control...

It simply looks like no power supply to indoor units (they are hard-wired to the outdoor unit). So I used a multi-meter to test the power terminals of indoor units (Danger! If you have no idea about this, don't even try! ): it seemed no power supply even C/B is on. I turned to the isolator which next to the outdoor unit. The isolator was making arcing noise when I switched it on and off. The indoor units suddenly turned on for few minutes then died again.

So I figured out the problem is that crooked isolator. I called the unhappy electrician to replace the isolator. End story....

I hope my experience will help you a little bit.

Oil filled heater won't heat up. It does turn on and the light illuminates but no heat. I't been in basement for the summer.

Could be that the thermostat is disconnecting because it senses too warm.

Plug the heater to the wall, turn on the switches.
Turn the thermostat knob all the way to min. It should make a click sound and the heater should not get warm.
Turn the thermostat knob all the way to max. It should make a click sound and the heater should get warm.
If the heater is still not warming up and/or you don't hear clicks, then the heater has bigger a problem.
With the cheap prices of the heaters, it is not worth trying to have an electrician check it out. Just buy a new one.

LOL no it seems to work properly . But with the heat wave going on it appears that you have the temp set to low . If the filter is clean and all other things are fine then try turning it up a few degrees but only after yo have de iced it.. also look inot the coils and be certain that they are clean . it's just all the heat and not the unit in my humble opion.

Delonghi dragon 3 oil filled radiator switch is on 0 but radiator is still on. only way to switch off is to switch off plug or unplug. Only had it for few weeks.

the switch acts like a thermometer, which turns it on according to the temperature. At zero I imagine the temperature setting is around 55, if it's colder it will turn on. Also, you will hear a hum any time the unit is on any setting because power is being introduced to the circuit, and is being rerouted by the switch.
In other words, that sounds like normal operation.

Bulb blew in my dimplex michigan fire, model MCN20. I now can't get the bulbs to switch off with either the remote control or the on/off switch.

Stewart, turn the Master ON/OFF Switch to OFF. Unplug the unit from the wall outlet and wait 12 - 15 minutes. Then plug the unit back in and turn the Master ON/OFF Switch to ON and set the function controls manually (not with the remote) one at a time. If everything works as it should, the fire reset itself during the 12 - 15 minute timeout. If it didn't or that problem continues to reoccur, contact Dimplex North America, Technical Service at 888-346-7539.

Hope this helped you solve the problem.

You have a PROBLEM that Dimplex USA, Technical Service wants to know about 888-346-7539. In the meantime, turn the Master Control Switch to OFF and unplug the unit. Do not use it again, until you have spoken with them.

Sorry I didn't have better news for you, but safety first.

Please be kind enough to rate my reply to you. Thanks!

My dimpex electri heater model 6902340100 suddenlt died. Is there a reset or a fuse to restore it to use? The main on off switched seemed to freeze in one position then the unit stopped working.

It just may need resetting. If you can, turn OFF the Master Control Switch and unplug the heater. Leave unplugged for 12 to 15 minutes. Plug the heater back in and turn the Master On/Off Switch to ON. If everything works as normal, then the heater successfully reset itself. If this continues to be an issue, unplug the heater and call Dimplex USA, Technical Service 888-346-7539.

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

Our dimplex electric fireplace model number 28106D3F shut off and won't turn back on

Turn the Master ON/OFF Switch to OFF. Unplug the fireplace from the wall receptacle and leave unplugged for 10 - 15 minutes. This will give it time t reset itself. In the future, if you finding you're have to do this more often. Unplug the fireplace, stop using it and call Dimplex USA Technical Service 888-346-7539 for further instructions.

My dimplex has a remote control box that plugs into the outlet. I haven't used it for a year or more. smelled something hot when it was on. the outlet & box was very hot, the bottom of the box was...

You definitely have an electrical problem either with the remote box or the the A/C unit itself. Something within either of the aforementioned is overheating and use of the air conditioner should be stopped immediately, as it is a fire risk. Unplug everything from the wall outlet and contact a service company that services Dimplex Air Conditioners. This is not a DIY fix!

Not sure solution, but try to unplug the air conditioner for about an hour, this will reset the configuration of the control program, then plug it again and try it.
