Question about Heating & Cooling
I have an Optimus dish heater model H-4438. The ALARM light is supposed to come on if the heater gets to hot. Even after it's been off for a day, when you turn it on the ALARM light comes on and the heater will not work. Any advice. There are no trouble shooting tips in the manual.
I have the same problem. I removed the center panel on the back of the dish and found a fuse inside a white insulating sleeve. The fuse is open, preventing the current from reaching the heating coils. On the fuse it says 121 C. and 15 A.; I assume that it is designed to blow if the temp. of the dish exceeds 121 centigrade or the current exceeds 15 Amps. I don't see any reason to believe that either has happened so I suspect that these fuses just spontaneously fail. Now I just need to find a source for new ones. I wouldn't recommend jumping the fuse as it could lead to a fire.

I have an OPTIMUS dish heater model H-4436. The heater was jolted and the alarm went off.
Now when I turn on the heater the Alarm light comes on emmediatly and there's no heat.
I've tried this many many times with no results. What can I do to get the heater operating again?
