JBWEB000309: type JBWEB000067: Status reportJBWEB000069: description JBWEB000124: The requested resource is not available. In this article, we'll discuss resetting the UniFi Access Point (UAP) to factory defaults. We'll discuss options to reset the unit via software, SSH, and physical reset. If the UAPs are adopted under the UniFi Software Controller, they can be reset from the controller. Via SSH, users can apply syswrapper.sh restore-default. The UAP should quickly reboot with factory default settings. Located on the back of the UAP is a small hole whereby a user can use a paperclip to depress the button and the UAP back to its factory default settings. You can refer to our UAP video tutorial, or follow the steps as outlined below: Press and hold the button for 10 seconds Release the button (the LEDs on the UAP will stop glowing) Do not disconnect the UAP from its POE injector during the reboot process The UAP will restore factory settings Once amber LED (or white LED, depending on your model) re-appears and remains steady, you can commence with UAP adoption.

First there two types of basic refrigeration switches in the typical high-grade residential system. I say high grade because not every refrigeration system in air conditioners and heat pumps have switches to protect the refrigeration system.

High-Pressure Refrigeration Pressure Switches - The high-pressure switch will kill the compressor circuit if the pressure exceeds the rating on the pressure switch. The ratings will vary depending on the type of refrigerant the air conditioner or heat pump uses in the system. On some air conditioners or heat pumps this switch is manually reset only simply because if it trips there is definitely a problem that needs to be resolved before the system should run again. On Rheem and Ruud heat pumps and air-conditioners, the reset button is usually red on located near the control panel. A simple push of the switch will reset the switch and the operation of the air conditioner should return to normal until the pressure exceeds the rating of the switch.Things that can cause the high-pressure switch to trip include:Bad condenser fan motorCondenser Coils plugged up with dirt and debrisFins on the coils bentBlockage in the refrigeration systemThese issues, if they exist, should be taken care of before the switch is reset.

The high-pressure switch prevents the system from operating at extremely high pressures. outside ac unit will not turn offContinuously resetting the switch without taking care of the problem will lead to possible catastrophic failure of the system resulting in higher repair cost. ac wall units with heatersLow Refrigeration Pressure Switches - The low-pressure switch is typically an automatically reset switch that will reset itself when the pressure on the low-pressure side of the refrigeration systems returns to normal or above the setting on the switch. new 5 ton ac unitWhen a refrigeration system operates at lower than normal pressures the system can freeze up with the freezing beginning at the evaporator coil and working its way back to the compressor via the suction line.

Freezing of the refrigeration system is bad and lead to liquid refrigerant slugging in the compressor which can lead to compressor failure. Things that can cause the low-pressure switch to trip include:Low refrigerant charge from a refrigerant leakBlower motor failure in the air handlerPlugged evaporator coils or a blockage of air flowFailure of a refrigeration component in the refrigeration system Again, if these issues exist in the refrigeration system they need to be addressed to prevent the low-pressure switch from tripping. In some cases such as catastrophic failure or loss of the refrigerant charge the system will not run at simply because the controls were engineered correctly to prevent short cycling however it is possible the system can short cycle especially if the condenser has been re-engineered with aftermarket parts by someone who knew enough to be dangerous. This includes myself in certain instances however I always do my best to think things through before making a change to the system.

After all, solving one problem only to create another problem is not fixing the HVAC system. Number one is safety and reliability and number two is protecting the system from permanent damage keeping number one in mind.These switches are used for a specific purpose and re-engineering the HVAC system can create other problems. It is also important that the person making the changes is competent or has someone competent review the changes to make sure other problems will not be created. When engineered properly these devices can protect the system and save you tons of money in the event of a catastrophic failure of the system for any reason whether it is a system defect or it is a child playing that damages the unit.You can learn more about refrigeration and HVAC here.Please help with hard-wired smoke detector issue... 1 2 3 4 5 6 7 8 9 17 18 NEXT 10 Times Doing It Yourself Doesn’t Save You MoneyAt least a quarter of all appliance repair calls are resolved with no-brainer solutions like pushing a button or flipping a circuit breaker.

Learn what to look for and how to avoid these expensive lessons. All disposers have an overload feature that automatically shuts off the power when the motor becomes overloaded and gets tooOnce the motor cools, simply push the reset button on the side of or under the unit. On the other hand, if it hums but doesn't spin, it may have something off, then try working through it by turning the blades with a special disposer wrench (sold at home centers) or by turning a bottom bolt. Many disposers have an Allen wrench for that purpose, inset on the bottom of the machine. When a light goes out or a switch doesn't work, you should first check the main electrical panel for a tripped circuitBut don't stop there. Before you change out light bulbs and switches, see if a GFCI outlet (which may be upstream from the troubled light or outlet) has tripped. Sometimes all the bathrooms or the outside lights are powered

through a single GFCI located in one bathroom or elsewhere, such as in a basement. Simply push the reset button on the GFCI and you could be back in business. If your refrigerator conks out on a hot day and you have a cat or a dog, immediately check the coils for pet hair. Service pros find this problem on half of their refrigeratorThe coils are the black tube-and-wire grid that cools the fluid in the compressor. A buildup of hair will cause the compressor to overheat and trigger the overloadOn many fridges, you get to the coils by opening the grille at the bottom of the refrigerator. coil cleaning brush (sold at home centers) into the coils, pull it back and vacuum it clean. If the coils are located on the back, pull out your fridge (it's often on rollers) and brush them off. Bonus: The clean coils will cool more efficiently and save you money on your utility bill! Once the overload switch is tripped, you may have to

wait a few hours for it to cool. It will reset itself and turn the refrigerator back on. If your stove burner won't come on, the likely culprit is the spaghetti sauce that boiled over a few days ago. Use a toothbrush to clean off food spills from the igniter. On an electronic ignition stove, it's a little ceramic nub located either on the stovetop or under the ceramic seal strike plate. Also make sure that the round ceramic seal strike plate is properly seated on If your electric stove burner won't heat, turn the burner off and pull it out from its socket. Then plug it in again and wiggle it around. If it feels loose, remove the burner again and gently bend the burner prongs slightly outward for a tighter connection. end up pushing the whole socket out of its bracket. Standing pilot gas range To access the ignition system in an older-style standard gas range, pop the lid. It's usually hinged on the back side.

If the pilot flame is out, poke a needle into the pilot hole to clean out soot (be careful not to ream it wider). off any debris and clean the tube that leads from the pilotThen relight the pilot. Blame it on the technology. It so happens that if you set the “time cook” function, the oven, much like a programmed VCR, won't turn on until the appointed time. have done this inadvertently, but if your digital display reads “hold,” “delay” or “time cook,” then the timer clear it first by pushing the dials, be sure the knob is When a washing machine cabinet rocks, it makes a horrible racket during the spin cycle. The solution is to simply readjust the legs. Screw the front legs up or down until the cabinet is level. legs are solid on the floor, tighten each leg's locking nut. washers, to adjust the rear legs, gently tilt the machine forward and gently lower it down. The movement will self-adjust the rear legs.

Our expert repairman responds to many “dryer-not- heating calls” only to find that the machine is set to “fluff air”—a non-heat setting. Check the settings first. Another common cause of poor drying is aThe filter may look clean, but it may actually be covered by a nearly off the heat before your clothes are dry. Test your filter byIf the filter holds water, it's past timePull out the filter and scrub it in hot water with a little laundry detergent and a stiff kitchen brush. Also check the outside dryer vent for any lint that may have built up there. door–style vent covers are notorious for lint buildup, which traps heat and turns the heat offPull the cover completely off to get If you turn your central air conditioner on, off and then on again in rapid order, chances are you'll blow a fuse or shut off a circuit breaker or the air conditioner simply won'tThat's because the compressor

(in the outdoor condensing unit) may have stopped in a high compression mode, making it difficult to start until the compression releases. Older condensing units may switch the compressor on anyway, which causes the circuit to overload and blow a fuse. “smarter” condensing units will prevent this blunder by delaying the AC’s “on” function for a few minutes. It's easy to mistake this delay with a faulty air conditioner. Be patient and give the air conditioner about five minutes to come back on. To determine if you have a blown fuse, locate the special fuse block near the outside unit. block and take the whole thing to can test the cartridge fuses and tell you if you need to replace them. Another simple reason your AC might not come on: You've signed up for a cost discount with your electric company in exchange for limited air conditioning during high-demand periods, and you're inIf you can't remember, call your electric company to
