F50E New Power Supply Arcing

I've just installed a new solid state power supply on an old F50E but it is arcing (clicking)continuously as soon as I power it. It does it with one or 2 cells but not without cells. The cells look OK (infinite resistance).

Check the fins on both cells for even spacing on the fins. If the fins are bent a little, this will cause your arcing.

Pull both cells out and reinsert them one at a time. Keep the cell all the way to the front or all the way to the back so it makes contact with the power supply.

The cell that has bent fins will continue arcing. Good luck.

Find out the electronic circuit voltage

I am an electrical engineer and I do not fully understand your question. If the unit is designed to operate on 50/60 Hz, it cannot be damaged by operating it at either of those line frequencies. Mnay products today will operate at either line frequency.However, if you used an adjustable voltage power transformer (a.k.a. "Variac"), you may have "under-voltaged" or "over-voltaged" the device. If there is a circuit breaker, try resetting it. Otherwise, there may be a circuit board-mounted fuse internally that is now electrically "open." That can be tested with an Ohmmeter for continuity. (Finding a replacement may prove difficult.)

Operating a line-powered device above or below its input limitations can permanently damage internal power supply functions and, perhaps, other circuitry as well.

Solid state components can fail "open" or "shorted." If they fail "open" they will not draw appreciable current to "burn" them in any obvious way.


The plastic insulators may have become dislodged. If the filter is fully dry, and it is arcing, look for plates that are nearly touching. and look for the distinctive black residue the arcing will leave behind.

Depending where the arcing is occurring, the cell may need to be replaced if inslutors have degraded excessively.

If hair or a dust bunny get in there, it is comparable to a bumble bee getting caught in a bug light zapper- it might take a while to clear.

Recently cleaned unit. now i am getting arcing on

The arcing sound comes from a loose fit. You may have to bend the contact bar so it fits tightly against the unit.

One of my Honeywell F50F cells (FC37A1130) arcs incessantly. Everything is clean, and I can't spot a broken wire, touching plates, or anything like that. The area of arcing is very definite (I looked...

I had a similar problem with mine. It looked to me like the vanes were fluttering and causing arcing. I found an old piece of comb and slid the tines between the vanes to stabilize them. You might have to try it several times to get the position just right. So far its worked for me.

After cleaning my electronic filter, it runs well for about a day. Then, it begins to continuously arc until I wipe the wires clean. Again, no arc for awhile, then, continuous arcing. Is there something I...

It is normal to hear occasional snapping from your Electronic Air Cleaner. This occurs when larger particles are caught by the ionizer wires. Continuous snapping is not normal however, and should be investigated as outlined below: Please note that the metal electronic cells may have some sharp edges; use care when handling the cells. Wear gloves to protect your hands from being cut if needed. Remove both electronic cells. Make sure that there is no hair, dirt, sand or any debris on the bottom inside the Electronic air cleaner. If there is, remove what you can by hand. If a lot of debris is left in bottom of the Air Cleaner, you may want to use a vacuum attachment to see if you can vacuum up what you can. Do not vacuum the Pre-filter or Post filter this may damage it. Close the access door, and then turn on the Electronic Air Cleaner and the system fan. If the snapping continues with the cells removed, contact your heating and cooling contractor for service on the unit and turn off the Electronic Air Cleaner’s power. If snapping does not continue, make sure the electronic cells are clean, dry and properly installed. Inspect the electronic cells for bent collector plates, broken wires between the plates, dirt on the insulators, and damaged collector contact tabs located on the top of the cells. Make sure the pre-filters are in good condition and are in the cabinet slot farthest from the furnace (The order of the Electronic Air Cleaner Filters are from the return duct to the furnace is: Pre-Filter, electronic cell, and then Post filter, if your Electronic Air Cleaner has one). If the snapping persists and you are unable to locate any physical cause, please contact your heating and cooling contractor for service on the unit and turn off power to the Electronic Air Cleaner.

Ionic breeze is arcing after it was cleaned. Let

sharper image has a class action lawsuit against them for the ionic breeze you should look into it

Red Light

slow blinking light means the unit is in DRY MODE.. flast blinking light means some sort of arcing or bad power supply..
if in dry mode let the unit run for an hour and it will stop blinking ..

Crackling sound

You need to look inside (through the front grill) with the lights turned off, and try to spot the sparking/arcing high-voltage - - what you're likely hearing is a spark where high-voltage is grounding-out due to a fault in the wire insulation or some other insulating structure.

Once you isolate where in the machine it's arcing, you may be able to determine where it is and whether or not it's within your skills to fix it. If it's an XL-15 as indicated by this category, it's no longer in warranty (no longer even supported by the manufacturer, for that matter, so it will be up to you to determine how much you want to work with high-voltage electricity.

If you can find the spark, you might be able to report back here for more detailed advice. Hope this helps.

Ionic breeze is arcing inside unit

I have a sharper image ionic breeze hybrid gp that ran fine for years unitl it recently started sparking / arcing at the base of the grid blades and always in the same spot. I cleaned it several times but the sparking always came back and the unit went into either "drying grid" or "attention required" mode. The solution I found was to stand the removable grid in 2 inches of Pine-Sol cleaner 50/50 diluted with water for 24 hours then brush again with the cleaning brush and hot water. Presto! No more sparking.
