    Default Nobo Panel Heaters - Anyone got them?



    I've had Nobo Electric Panel heaters for the past 10 years, they have worked great... a bit $$$ to run, but quite and safe....

    After this time, all my Nobo panel heaters have died. Fail to turn on.
    They have the digital clock on the top right and a white on/off switch on the lower right.
    I did pull one apart a while back thinking it would be an easy fix... but man it sure wasn't.
    No visible signs of failure, no burnt connections... infact, everything looked great.
    And with very few parts... there isn't much to go wrong.
    Element, iso switch, thermo, O/T cut out..... and a timer.. thats about it.

    Anyone had any experience repairing these heaters?

    A friend of mine is an Agent for repairs in Punchbowl/Sydney. It's most likely the timer on top or the thermostat panel at the r/h side bottom.
    Where are you located?

    Default Nobo Heater (Timer or Thermostat?)

    Hi there, just wondering if you figured out what the problem was/is? We have the same heater (timer on top, thermostat on the side).

    Timer works perfectly, (red light comes on, all digital display works etc), but heater wont turn on (ie red light at thermostat wont come on, and element does not heat up).

    To me, logically, it must be the electronic thermostat circuit board on the side of the heater. Given the fact that the timer works perfectly, (red light and all), and the red light for the thermostat does not, the problem must be there.

    I got a price on the thermostat board for these from a Nobo parts supplier - $176 !!!

    Did you end up asking your friend what the most common problem with these is?

    Thanks in advance,
    Chris

    Thanks guys, i have been in Melbourne all week and haven't time to pull them apart.
    When i do, i'll post pics of the procedure and parts found inside.
    From memory, there isn't much to them...

    I'd be happy to just turn mine into full manual heaters and by-pass the timer all together (as it seems its the Timer that has failed, and as such, no power to the element)

    Will be interesting, i'm really surprised more people don't have them???
    We installed 100's down this way... then again, we don't have town gas like you city folk
    Yet even then, i have seen entire apartment buildings in the city using Nobo Panels for heating. Heaps up at the snow too... and they are all about the age where heaps should be failing

    It is most likely the black(transistor?) mounted to the heatsink which switches the neutral to the element.Hope this helps.Or the dble pole rockerswitch,check it for burnmarks.

    Default Nobo Heater Timer Issues

    Guys
    I'm new to this forum and I also have a 2000W Nobo with the timer
    the same as Oceanboys. I brought 4 of them 6 years ago (just prior to
    the 7 year warranty upgrade they now have). My units are now not covered
    by warranty. I also asked our parts agent/warranty guys in Mildura about
    ordering a timer unit and after contacting Nobo they say the timer can not be
    purchased, What the ....
    I yanked mine apart but can not see anything wrong with it. The timer works,
    the heater does not.
    I am also wondering what to do with this unit.
    Any help would be appreciated.

    Default New Nobo thermostat fixed the problem

    FYI - At the end of last winter I ended up purchasing a new Nobo thermostat (got it for $130 from Marks Electronic in Hoppers Crossing)...I removed the old thermostat, fitted the new one (was VERY simple). It fixed the problem perfectly and the heater worked great for the last few weeks of winter.

    Have just got it out of the cupboard tonight, plugged it in - still working perfectly...but now the timer has no display! Lol...hoping it just needs to recharge its internal batteries a little longer...I'll check it tomorrow morning.

    Well, at least the heater actually works...thats the main thing. I dont care so much about the display.

    I purchased a couple of 2000w Siemens Panel heaters with the manual thermostat so as to avoid this common problem with NOBO. Does not help the ones with issues now but gives a heads up to prospective buyers of these units.

    Interesting some people suffered the issues as myself.

    I've killed losts of panel heaters, not just Nobo, the IXL Pacific that replaced one of the Nobo's didn't even last one winter.

    Its a pity, i am installing these units by the dozens at a time in new homes and they just seem to fail.

    I had another client come to me with a Nobo heater that was suffering the exact same problem as mine. I told him to take it to a Nobo dealer, his quote to fix it was only $80 short of buying a replacement unit.

    The ONLY panel heater i own that hasn't died is an old Siemens one, and mean OLD!

    I am pretty hard on them, i have 3 that are on 24/7 for 4 months at least.
    With the Nobo it is the LCD controller that fails every time.... and for some very unfortunate reason, all the external controls like thermostat trim pot hang off the controller, making it impossible to just by-pass the controller and run the heater with just a isolation switch and thermostat.
    Thus rendering the heater useless until the controller is replaced... But why replace something that will only fail again!!!!

    Anyway, my symptoms have been similar to some posts above;
    - Failing LCD clock display which holds the relay for element.

    Really is a shame these Nobo's can not be retro fitted with a simple 10Amp thermostat, and just piss off all the LCD junk.

    Must be a solution, as the Non LCD Timer units get the job done!

    Oh well... time to rip these things apart again!

    I brought my Nobo second hand and found the timer had issues. Pulled apart and found back up battery was dead flat. Installed new larger NiCd and put back together. Plugged in heater to charge new battery and all fine. The timer needs constant 230V to keep battery charged.

    Yep... that is exactly what it sounds like... like dust burning off, then it settles.
    Or... bad contacts

    I know it's internal but have never changed one so am unable to advise.

    I dont want to damage it like I do with most things.
    If you mean that literally, it sounds as if you lack appropriate experience in working with electrical appliances. That being the case, you would be well advised to get it serviced by an appropriate repairer.

    Nobo can be contacted at .

    Their website lists repairers for all Australian states.

    Hi, I have the exact same issue where the battery has died on the LCD screen but the heater still works.

    I've taken apart the LCD but can't locate the battery. I've also taken apart the radiator and still can't find the battery.

    Is there any chance you can tell me where the rechargeable battery is and of what type?


    Many thanks in advanced!
