My Honeywell 17352 quit working, and the lcd display was frozen (it did not respond to any of the buttons being pushed). This break-down came after a very brief power outage. I un-plugged the unit, and still no response, so I plugged it back in, removed the battery, and unplugged it again. Now the display shows a row of 10 empty adjacent squares, and there is still no response, in the display or the fan, when any of the buttons are pushed.

SOURCE: Will not start up??

there is only one other thing that i can think of that might work ifyou haven't done that yet. right above the timer button there is a small pin hole. that is your reset button. you need like a safety pin or something really small to go in that hole. hold it for about 3 seconds. take the pin out and the system should reset back to normal. sometimes when you clean the filters that happens. not every time but sometimes. Now if that doesn't work. i would call the manufacturer again so see if they have any other solutions or if they can send you one more. I do apologize for the inconvenience. I will keep looking for you to see if there is anything else that i can suggest but try that first.

When was the last time the backup battery was checked? The trouble indicator could mean a weak or non-working battery. If the system is 12 years old, the battery should be changed.

Hello,

Check to see if there is power getting to your device. If it is a 110-volt unit, plug a lamp or other device into the same outlet the device is plugged into. If there's no power, check the fuses or circuit breakers. If there's still no power, you will need to contact a qualified electrician to restore power to the outlet. If there is power to the appliance but it is still completely dead there may be a problem in one or more of the following areas: Wiring (Inspect for any broken or burnt wiring) Selector switch Control board Work on these areas of an appliance may require help from an appliance repair person or other qualified technician.
Take care.

I have a similar unit. For the price they should be self cleaning and cook for you too! What I would try is Radio Shack for some Anti-static cleaning cloth and Electric contact spray. You would not want to spray too heavy on the display or it may get muddy looking.

If this does not have an effect, my UV light went out and set a screen to replace it. But this was after several months of cutouts and automatic restarts. Judging by mine, the light was the problem and should have coded earlier.

These are expensive units. The brain and reset button may be Static charged. Besides you ordering a new panel, a computer repair shop may be able to get into the circuit board and demagnetize it. They are use to working on Digital panels and circuit boards. I feel the same precautions for cleaning should have been recommended by EcoQuest as those for computers. Static-free cleaning areas and tools.

I hope my solutions help you get your unit fixed.
