Central A/C will not turn on

My central a/c will not turn on. There just seems to be no power to the entire unit. Checked fuse box in house everything okay there. Could this be a bad thermostat? What should I check before calling for service/repair?

There is usually a small fuse inside the indoor unit(furnace or air handler). That fuse generally is located on a circuit board and looks like a car fuse. It may be amber or purple in color. This fuse may have blown. If so you may have a bad circuit board. I recommend calling a NATE certified Tech for service as this one has several possibilities. Good luck.

Nutone cv353 unable to stop


You may have a stuck relay or one of your access port switches may be bad. According to the owners manual: "A complete check of all Wall Inlet and Power Unit low voltage control lead connections (external yellow leads). Turn system off by removing fuse or tripping circuit breaker at
house fuse box."

Have a ford f 350 2004 model manual ****** motor wont turn over replaced clutch safety switch ck starter relays can b pull started


Did you check for power at the starter ignition terminal? It is the small YELLOW/BLACK wire on the starter. If there is power there, replace the starter. If there is no power there, you should check your starter relay an its associated fuses.
The relay primary side is protected by fuse number F2.31 (15 Amp) in the Central Junction Box. This fuse provides power to the clutch safety switch on the WHITE/PINK wire. Then the power leaves the clutch safety switch on the TAN/RED wire and goes to pin 86 on the relay.

The relay secondary side is protected by fuse number F2.113 (30 Amp) in the Central Junction Box. It provides power at pin 30 on the relay, which is also located in the Central Junction Box.

Pin 87 at the relay is the YELLOW/BLACK wire metioned earlier and goes to the starter motor.
Pin 85 at the relay is the primary GROUND. This should be ground at all times.

The ENTIRE starting system can be checked/diagnosed from the pins at the starter relay if you use the correct methods and equipment.

When we turn on the central air there is a strong burning smell...like burnt toast but way stronger. IS it safe to remian in the house?


Is your central air furnace or electric heat. Electric furnace sometimes have electric strip sequencer stick in the closed positions leaving on one strip of the electric heat. Get a service tech as soon as possible to check this out. Any smells from a central unit need to be teken care of promptly. TURN OFF unit you have it checked for your safety. Rus

Easy Flo Central vacuum will still work at about


Yes you can easily test for a clog, and a crack for that matter.

to test for a clog push a dry garden hose through the entire system until it comes out at the other end.

to test for a crack, Disconnect the pipe that comes from the house to the central vac unit. Turn on the unit and put your hand over the opening directly at the central vac unit.(Using the utility inlet at the unit will not accomplish the same thing.)
  • Step 2 If your suction is good, then reconnect the tubing and turn on the switch at the unit. If there is no switch, plug your central vacuum hose into one of your inlets to start the system. Then have someone completely seal the hose with their hand. While the unit is running go to the exhaust. With everything closed you should feel almost nothing coming from the exhaust. If you feel very little exhaust, then you do not have a leak

    Central Vac will not turn on.


    These problems are nearly exclusively caused by a bad circut board and replacing it is the fix. Bad boards can cause many different effects so its nearly impossible to be sure. The 9v signal wire is not enough to short out an entire unit so it is unlikely the hose. If it is a direct connect system and you are pulling power from the 110 somehow that would cause main unit problems but that is unlikely at best. Sounds like a failed board to me.

    Best of Luck

    Electrical fault


    Malsmed,

    Does your mazda have a central locking unit in the boot? If so then follow the wiring if you can to the fuse block and see where the wiring goes into and check the problem their? If that does not solve the then check the central locking unit in the boot and the ECU unit behind the fuse box.

    Hope this will help you
