Honeywell oil heater HZ680

I noticed last year that oil was leaking around the fins and wonder if this heater is safe to use, any solutions? thanks

    The oil is slowly leaking out of bottom of the heater and staining the wood below. How can westop the leak

    I know someone suggested to replace the heater, it just seems like there should be some way to repair a small leak and keep one more thing out of the landfill. Anyone?

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!

My Honeywell HZ 709 WMT stopped working. I've had it for about a year now and has been great up to this point. Any ideas?

I am having the same problem. I am not sure the cause but I was reading that some manufacturers will put automatic shut off switches in the electronics. I read that it was mainly printers and faxes but I wonder if that could hold true here as well?

Will not turn on. Unit has been working great until tonight. Was on but now off and will not come on. Unpluged it for an hour but still not working.

This same thing happened to me, and yesterday as well no less. I've had mine for a 3-4 years. I think It had run out of oil, which is weird because I've had a Holmes heater for nearly 10 years and it still has plenty of oil left. If you shake it, can you hear the oil? I went and got another from Target last night (it was the coldest night of the year) and can hear the oil swishing around in it as I set it up. Hope it last longer than another 3-4 years or my next one will be a Holmes.

It is 22 degrees here in Dallas, Tx and my heater doesn't seem to want to get it any warmer than 67 degrees. My unit is only a couple years old along with my Honeywell TH6220D. Just wondering if it could...

em means emergency heat,which means you have a heat pump.check out door unit,it might be all froze up,or covered in snow,sweep snow off gently. if it's froze up its not defrosting and you need a service call.if your back up heat is not working there might be little window on furnace,look for flashing light inside.if light is steady on its working.
