How to Replace an Electronic Control Board in a Window Air Conditioner This step-by-step repair guide shows how to replace the electronic control board in a window air conditioner. The control board is the “brains” of the window air conditioner. It monitors sensor and activates components as needed to cool the room and maintain the set temperature. If the electronic control board is defective, replace it using a manufacturer-approved replacement part. Less than 45 min. Wear work gloves to protect your hands. Warning: Undertaking repairs to appliances can be hazardous. Use the proper tools and safety equipment noted in the guide and follow all instructions. Do not proceed until you are confident that you understand all of the steps and are capable of completing the repair. Some repairs should only be performed by a qualified technician. Unplug the power cord from the wall outlet. Remove the screws that hold the accordion filler panels in the window frame.

Push the accordion filler panels inward to clear the window frame. With someone’s help, support the air conditioner and raise the window sash. Carefully lift the air conditioner out of the window and set it on a stable work surface. Grasp the sides of the front grill panel at the top and pull the front grill panel out and off of the air conditioner. Pull out the filter. Tip: Take this opportunity to clean the air filter if necessary. Remove the screws from the sides and bottom of the control panel. Pull the control panel up and hold it above the air conditioner while you unplug the wire harness connection for the user interface control board. Set the control panel aside. Remove the screws from the sides of the front panel. Pull the front panel off of the air conditioner and set it aside. Remove the screws from the exterior of the outer case. Remove the center stop for the accordion filler panels. Remove the hidden screw that’s under the center stop.

Pull outward on the bottom of the outer case and remove the outer case from the air conditioner. Remove the screws from the electronic control board case. Pull the cover of the electronic control board case out to expose the electronic control board. Take a digital photograph or otherwise document the location and routing of wires connected to the electronic control board so you can connect the new one correctly. Pull all wires off of the electronic control board. Remove the mounting screws that hold the electronic control board in the case and pull out the electronic control board.

Plug the air conditioner into the electrical outlet. A buyer should ask ONLY for things that if not done, they would back out of the purchase of the home. This is a unique and personal choice based on the circumstances.... and that's the type of advice and guidance a good agent can give you because they've been there with you thru the whole process. Some buyers try to "get something" from the seller just because they think they can. Some Agents try to enhance their buyer's bargain by "seeing what they can get" from the seller. I find both approaches distasteful, dishonest and synonymous with stealing. The home inspection is designed to give the buyer a chance to back out of a deal if they discover a major problem and to give the seller an opportunity to resolve a major problem that's just been discovered. The home inspection is NOT an opportunity to give the seller your laundry list of repairs or improvements that you want done! This is NOT an opportunity for you to enhance your bargain.

This is NOT the time to address repair issues that you could/should have seen with your own eyes before you made your offer. This is NOT the time to cover your own lack of home repair experience, your fear of home repair uncertainty or your lack home repair dollars by trying to shift YOUR responsibilities to the seller. If you bargained for an inexpensive home that needs work, that's what you should get. If that's not really what you want or what you can handle, then you should back out of the purchase and find another home instead of trying to get something for nothing from the seller. Remember, ONLY ask for the items you're willing to back out over. That's not to say those items will be "reasonable" or even acceptable to the seller, but you will know exactly where you stand on the purchase and you won't have any regrets later if you get the house or not.

Serving Gloucester Twp, Washington Twp & South Jersey Real Estate Markets Agent, Basking Ridge, NJ You should expect that the seller will address matters that present structural, safety, or environmental risks. This would include any structural issue with the foundation, safety would involve things like electrical/wiring issues, and a good example of environmental would be a high radon level. The home's mechanical systems and appliances are to be in working order. If the furnace is old but functioning, then I do not think it likely that they will replace it, ditto for the air conditioner. Now if either is not working, then I would expect them to repair. A standard seller's disclosure includes the age of the mechanicals, and so you should have known that the system was old and possibly near the end of its useful life when you made your offer. Windows with broken seals is not an uncommon issue, and I would add it to the list of requests - they may replace or throw some money your way for this.

Sidewalk cracks - I doubt they'll do anything here, unless it presents a safety issue, then I'd surely ask. I have seen requests for grading to take water away from the home - the case for action is more compelling if there is water in the basement than if not, but you can certainly ask. Another idea for the furnace and A/C issue is to request a one year Home Warranty, paid for by the Seller and being put in your name at the time of the sale. Be sure that coverage is adequate to cover the furnace and a/c. This will also cover the appliances. What I advise my buyers is this - a handful of items that you really care about is far more likely to get action than a laundry list of every deficiency noted by the inspector. Unwavering Commitment to Service Home Buyer, Chicago, IL Here again agree with Deb - the broken seal, while I see it on many inspection request lists, fact is it is visible to the eye and not a structural matter. And so you should build the issue into your pricing.

While it is unsightly and will grow with time, it does not impact the working of the window. Focus on the important things and do not use this as an opportunity to renegotiate - if you do that you will make it to the closing table, if you do the later, it is anyone's guess. I'm find a bit of a back-lash as sellers are growing weary of heavy handed buyer response to inspection issues. Of course, it is cyclical, we all remember the headiness of sellers refusing to do anything when the market was flying - ah, what a world!! Home Buyer, New York, NY Home Owner, Salt Lake City, UT Home Owner, Columbia, SC It sounds like the unit at that home is in pretty bad shape. I would say it needs some repairs at least. If it still runs fine than I would think that that would be acceptable by the owner. Home Buyer, Walla Walla, WA , Silver Spring, MD Sounds like quite the old home! Home inspection could cost a lot depending how much is needed to be done. Best bet would be to call a local company and get a quote.
