Try a regular hair comb to start with, and see if that doesn't help open them up enough.

Fujitsu airconditioner multihead c notworking

Dear Sir:

If your condensing unit has coils that are bent, they should be straightened out as much as possible for proper performance of the unit. You cannot straighten the fins properly without a special tool called a fin comb. These tools come in a variety of styles including single, multiple or interchangeable heads having different fin comb sizes and counts to best match the coil fin size of the repaired unit

sincerely. God bless you

Evaporator coils are freezing up. I took off the side cover and it is a solid sheet of ice covering 90% of the coils.

Hello, ice will form for one of two raesons, either low airflow or a low refrigerant charge. Start by checking the filter to make sure it is clean, then check the blower wheel and make sure it is clean. If the unit is clean then the unitnis low on refrigerant and will require a hvac tech to come out and recharge the unit.

My cooling coil ices up after running for a while , also ice develops on the condensor unit line.

Sounds like you have restricted air flow through the evaporator, which turns it into a mini-freezer. If the filter is clean and in good shape, I would check the evaporator fins on the air inlet side for dust clogged fins. You can brush them with a fin comb to clean them.

Ge tpx21pr side by side refig/freezer Freezer is not cold enough

If your unit is NOT a static condensor, (the type with cooling fins and tubes on the outside of the back of the unit) If the door seals are okay and sealing properly, you might need to service the forced air condensor components located at the rear lower area, usually behind a fiber board cover. Remove the cover and look for dust on the condensor fins and fan blades. If clogged, carefully brush, vacuum, or blow the dust out, opposite the direction of the fans natural air flow direction. (You don't want to lodge the debris further into the condensor fins.)..Be sure to unplug the unit first.

Bulb failure pasrking light

Taillight bulb needs replacing, high above brake light at approx height of bottom of side widow.
Remove plastic panel at interior rear corner, remove thin backing insulation and reach up with fingers between metal flanges. Feel for a plastic "fin" approx 3" long x 1" wide that is attached to lightbulb. Similar "fin" for brake light is visible (white color). You need to feel above this. Fin is probably gray color, but you can't see it. Twist slightly counterclockwise and pull out. Bulb is attached to end of "fin". Insert new bulb and replace.

Pressure keeps dropping on my jaguar boiler, no leaks in house but hot water coming from overflow outside

hi In most air-conditioning systems, the condenser unit is located outside the house and is prone to accumulate dirt and debris from trees, lawn mowing, and airborne dust. The condenser has a fan that moves air across the condenser coil. You must clean the coil on the intake side, so, before you turn off the power to the air conditioner, check to see which direction the air moves across the coils. Here's how to clean the condenser:
Step 1: Cut down any grass, weeds, or vines that have grown around condenser unit; they could be obstructing airflow.

Step 2: Clean condenser with commercial coil cleaner, available at refrigerator supply stores. Instructions for use are included. Flush coil clean (do not use hose); let dry.
Step 3: Clean fins with soft brush to remove accumulated dirt. You may have to remove protective grille to reach them. Do not clean fins with garden hose, as water could turn dirt into mud and compact it between fins. Clean fins very carefully: They're made of light-gauge aluminum and are easily damaged. If fins are bent, straighten them with fin comb, sold at most appliance parts stores. A fin comb is designed to slide into spaces between fins. Use it carefully to avoid damaging fins.Step 4: Check concrete pad on which condenser rests to make sure it's level. Set carpenters' level front to back and side to side on top of unit. If pad has settled, lift pad with pry bar or piece of 2-by-4, then force gravel or rocks under concrete to level it.

Bent grates on the roof unit how serious of a problem is it??

That is what removes the heat from the hot gas, if bent or pluged, it will make the system work a lot harder. Just take a knife and straighten them back, or go to a supplyhouse for ac and ask for a coil fin comb to straighten back out fins on a coil!
