Faulty Button

The vast majority of doorbell electrical failures will ultimately track back to a faulty button at the door. Remove the button and check the two wires in the back that should make contact when the button is pressed; if one is broken or out of place, you’ve already identified your problem. Otherwise, try touching the two wires together and see if your doorbell rings.

If it does, the problem is in the button and you should simply pick up a new one. If there’s an obvious issue with the wires, it’s almost certainly a job for your electrician!

Bell Unit

Once you’ve eliminated the possibility of a problem at the button, your next stop should be the bell unit or chime housing. Start by looking for the obvious once you’ve removed the cover: anything not attached securely where it ought to be, or corroded, or worn, or otherwise damaged. If nothing pops out, you’ll want to test the electrical connection with a low-voltage tester.

Connect it to the common terminal and one of the doorbell terminals, then have someone press the button at that door—if it lights up, but doesn’t ring, the problem is in the bell unit. Sometimes a thorough cleaning will get a unit working, but otherwise it’s time for a full replacement.


If obvious problems with the bell unit don’t show themselves, your next stop will be to look for the transformer and see if it has any problems. It’s important to note that this is where you move from the low-voltage systems of your doorbell to the much higher voltages of general home electricity. You can test the transformer with a low-voltage tester via screw terminals, but if it turns out to be the problem it’s almost certainly time to call an electrician.


At this stage, you’ve eliminated the button, the bell unit, and the transformer and found nothing wrong. If nothing pops out in any specific component, you need to check the wires running from your doorbell to the bell unit, and from the doorbell system to the transformer. Even the smallest problem can introduce enough disruption to prevent your doorbell from ringing..

Resolve Your Doorball Problems with Hoffman Electrical & A/C

If even an exhaustive search of the wiring of your doorbell still doesn’t reveal a problem, you’re probably dealing with some issue of the underlying electrical system. At this point, there’s not much you’ll be able to resolve on your own, even if you’re comfortable with DIY—electricity gets dangerous when you start looking at problems outside of the low-voltage system of a doorbell, after all. Definitely leave it to an electrician if it reaches this stage.

Breaker Panel Troubleshooting

Dealing with constant breaker trips, or have a breaker that refuses to reset in your control panel box? Our team knows well just how maddening this can be, and it always seems to happen at the worst time. Let’s see if we can’t help you out! Follow along with the certified electricians at Hoffman Electrical & A/C in St. Petersburg to find out how to troubleshoot your breaker panel problems.

Starting Off Easy

The good news is that the most common causes of breaker panel trouble are actually quite simple and easy to address. The majority of the time it’s a simple standard trip, and thus can only have a handful of triggers. We’ll start with these:

Attempting to Reset Your Breaker

Breaker trips are frequently a minor consequence, and can be easily remedied by simply resetting the breaker at the panel. The process to do this is easy, and goes as follows:

  1. Carefully open your breaker panel to expose the breakers that correspond to your home circuits. Be careful to listen for any buzzing or other odd sound,s and if you hear any stop messing with the breaker and call in an expert right away.
  2. Locate the circuit you’re trying to reset. There should be an easy to use diagram that uses numbers printed on or on the side of the breakers and printed locations throughout the home (utility room, Kitchen, bath, lights, etc).
  3. If the breaker tripped the switch located on it should be somewhere in the middle between “on” and “off” and should have a bit of springy give if you poke at it.
  4. Firmly push the breaker into the “off” position, count to three, and then set the breaker switch to the “on” position.

This may handle your problem right away, and if so that’s great! But if not, or if the breaker continues to trip without any input on your part then it’s time to call in an electrician. It’s possible that you’re dealing with damaged wiring, a failing breaker, or you may need a heavy up service to accommodate your growing electrical access needs.

Why Is My Smoke Detector Beeping?

Smoke detectors are wonderful devices. They save homes and property, prevent countless fire-related deaths, and alert people to potential fires before they are out of control. In fact, these alarms are so invaluable, many insurers offer discounts on homeowners coverage for homes equipped with working smoke detectors.

There’s no debate about the worth of smoke detectors in preserving the safety of your home and family. But, is there anything more nerve-shatteringly annoying than a smoke detector that won’t stop beeping? You know you’ve changed the batteries the last time you moved your clock. Your unit is fairly new, so it shouldn’t be failing. No one is frying bacon or burning toast. So what is it? What is causing this life-saving device to aggravate you to the point of knocking it off the wall with a broom?

Is the Noise a Chirp or Beep?

There can be many causes of a beep-happy smoke detector. The first thing you need to do is determine what kind of “beep” you hear. Is it the loud, long beep that warns you of the presence of smoke? Or is it a bit more “chirpy”?

Chirpy Noises

A “chirpy” sound coming from your smoke detector is very likely a warning that your battery voltage is low. Even though you’ve been diligent about replacing your batteries, you may have purchased a faulty or out-of-date battery, or significant temperature changes could have depleted your battery’s voltage. Be on the safe side and replace your battery with a brand new, non-expired one. It might be a hassle, but you need a fully operational smoke detector for your own safety and the safety of your family.

Random Beeping

Random beeping is another kind of annoyance produced by a faulty smoke detector. There are a few reasons your smoke alarm may be going off when no smoke is present.

Professional Smoke Detector Installation

Certified electricians understand just how essential it is to have working smoke detectors in your home. Your electrician can assess your home to ensure you are thoroughly protected. Placement of your smoke detectors is just as crucial as functionality, and part of the services provided by a professionally installation.

Don’t second guess your safety. Professional installation by a certified electrician is the most thorough way to ensure your home is alarmed against fire and smoke. When your smoke detector is hard-wired to your home’s electrical system, and has battery back-up, you’re provided with much more than thorough protection against a devastating house fire, you’re provided peace of mind.

If you’re experiencing trouble with your home or business’ smoke detectors, give the electricians at Hoffman Electrical & A/C a call!
