20 Most Recent Honeywell HZ-680 Oil Filled Radiator Heater Questions & Answers

here is a REAL solution... as i just fixed this myself... what you need to do is take apart the heater... this is easy to do, all you need is a screwdriver for this part... on top there is a panel, this can be taken off with a butter knife if you dont have a screwdriver... anyways, underneath this panel are 2 screws, take those out, flip the heater upside down, and take out the other two screws... now the whole side panel will come off... after that, you pull all three plugs off the thermostat with the heater on the flat side opposite, next use a pinch pliers to remove the bolt that the the plugs were just attached to, the next part they tell you not to do, well i guess they tell you not to do any of this... lol... but yeah, put engine oil inside... it heats the same as the heater oil... put the plug back in, and use Liquid Nails clear sealant under the electrical stuff (do not put it on the metal part surrounding it as this will be come a fire hazard then) reconnect the plugs in the order you took them off from (white one is on the bottom) put the heater back together and you are golden! XD hope this helps!

Oil Filled Radiator Heater Leaking

These heaters last about three years,and are throw aways,unless you have some in the ole shed like I do.Checking the switches is the first thing to do,remove them to see if they are burned up on the other side where the connection is.If they are,that could be the smell,or the thermostat is melted down,and smelling,again,throw away,,or save it,and buy a new one,and you will have parts for when it goes out,if the switches are melted down,a compatible switch,if found,can be replaced in the heater,but something made the switches melt down,most likely a heating element in the tanks,non replacable.

If it is leaking ,when it gets low enough,the heating elements will burn up,it is best to trow it away,and buy a new one,getting parts for these are an act of congress and you can buy a new one for the cost of repairs,and the tanks can not be fixed,or filled.

I would just use a good warm water and soap solution and rinse it with warm water. I would take care around the electric controls on the front panel so as not to have water enter. I would not use any solvents, as they can eat the plastic and possibly ruin the paint finish.

Pl check the manual. There are certain heaters designed this way! I can not comment unless the manual is read.
