Fixing your flammable vapor sensor lockout reset honeywell

Getting stuck with a flammable vapor sensor lockout reset honeywell situation usually happens at the worst possible period, like right before you need a warm shower upon a Monday early morning. If you're searching at your hot water heater and seeing a specific blinking light pattern—usually seven flashes—it means your Honeywell gasoline valve has made a decision to shut everything straight down for safety. While it's incredibly frustrating to have no warm water, that small sensor is actually doing a pretty important job. It's designed to identify if there are usually any combustible fumes near the water heater that could potentially begin a fire. However, these sensors can be a little bit oversensitive, or they might trigger because you were just doing some heavy cleanup or painting nearby.

The good news is that you can usually fix this yourself without calling away a technician and spending a couple of hundred dollars just for them to turn the knob. When all of us get into the "how-to, " we need to be smart about this.

Why do your sensor lock out in the very first place?

Before you even think regarding a flammable vapor sensor lockout reset honeywell treatment, you have in order to understand why the sensor tripped. This isn't just me being cautious; it's a matter of keeping your house from blowing up. These types of sensors are part of the Flammable Vapor Ignition Proof (FVIR) system. They will pick up on things like gasoline, paint thinner, turpentine, or even a few heavy-duty floor cleaners.

If a person recently spilled something in the garage area or if you were using the lot of spray paint near the particular hot water heater, the sensor did exactly exactly what it was intended to. It sensed all those vapors and reduce the gas to prevent an explosion. If you smell gas at this time, stop reading this, get out of the house, and call the particular gas company. Yet if the air flow is apparent and you think it was just a fluke or perhaps a reaction to some cleaning supplies, then we are able to move forwards with the reset.

Sometimes, also high humidity or perhaps a very dusty atmosphere can mess along with these sensors. In case dust builds up on the sensor, it can't "breathe" properly, and it might throw the fault code. In case you've checked the area and almost everything seems dry and fume-free, you're likely dealing with the "hard lockout" that requires a manual reset.

Identifying the Honeywell flash rules

Most contemporary Honeywell gas valves (like the well-known WV8840 series) use a single DIRECTED light to communicate what's wrong. It's like Morse code but for devices. If you have a flammable vapor issue, you'll typically see the light flash 7 times, followed by the short pause, then seven times once again.

This unique 7-flash sequence is the "Flammable Vapor Sensor Lockout. " As opposed to some other errors that may clear on their own after the problem will go away, this is a "hard lockout. " It means the system won't just begin working again even in case the vapors vanish; it requires a particular manual sequence to prove to the computer that the individual has checked the particular situation.

The particular step-by-step reset procedure

Alright, let's get into the actual flammable vapor sensor lockout reset honeywell actions. There are a number of ways to do this depending on the specific model of your Honeywell valve, however the "knob-turning" method will be the most typical for the particular electronic ones found on brands such as AO Smith, Rheem, and Bradford Light.

  1. Preparing : Make sure the area is usually well-ventilated. If presently there were fumes, open a window or door and let the space atmosphere out for a minimum of an hour. In the event that the sensor nevertheless "smells" the vapors during the reset, it'll just lock out again immediately.
  2. Turn the particular Dial to Away from : Start by turning the temp adjustment knob most the way to the "OFF" position.
  3. Wait a Moment : Give it about 30 seconds to the minute.
  4. The Sequence : This is the part that seems a little like the secret cheat code in a video gaming. You need to rotate the knob via different temperature configurations inside a specific time-frame.
    • Turn the knob to "Low. "
    • Then turn it to "Very Warm. "
    • Then back to "Low. "
    • Then back to "Very Hot. "
    • Finally, turn this back to "Pilot" (or "Low" with respect to the specific instruction for your model).
  5. Check the Gentle : You usually need to finish this back-and-forth rotation within about thirty seconds. If you achieved it right, the particular status light should change its flashing pattern. Instead of that annoying seven flashes, it will start a normal, slow "heartbeat" flash (once every few seconds), indicating that the particular unit is back in normal standby setting.
  6. Relight the Pilot : If your design requires manual lighting, follow the regular pilot lighting directions around the tank's label. Most modern Honeywell regulators have an integrated igniter, so you'll just support the knob straight down on "Pilot" and click the igniter button until the light starts blinking the "everything is okay" signal.

What happens if the reset doesn't work?

If you've attempted the knob-turning dance three to four times plus you're still viewing those seven whizzes, don't throw a wrench at the particular tank at this time. There are a few reasons why the flammable vapor sensor lockout reset honeywell might fail.

First away from, the sensor by itself may be "saturated. " When the vapors had been really strong, the particular chemicals can actually layer the sensor. In this case, it's not just reporting a problem; it's bodily compromised. You can try getting the sensor out there (it's usually a little plastic component on the very bottom of the water heater with two wires attached) and blowing this out with some compressed air. Be gentle, though. In the event that it's oily or even visibly dirty, a person might just require to buy an alternative. They aren't terribly expensive, usually close to $20 to $50.

Another typical issue could be the wires. Check the two wires that lead from the sensor backup to the Honeywell gas handle valve. If they're loose, pinched, or even have been chewed on by the rogue mouse, the particular system will trigger a lockout because it thinks the particular sensor is lacking or broken.

Testing the opposition

If you're a bit more DIY-savvy and have a multimeter, it is possible to test the sensor. Disconnect the wires and check the opposition (ohms). A healthful Honeywell flammable vapor sensor usually states somewhere between 9, 500 and 45, 000 ohms under normal conditions. If your own meter shows "OL" (open loop) or even a crazy low number, the sensor is toasted and no amount of knob-turning is going to fix it. You'll require a brand-new part.

Tips to prevent long term lockouts

As soon as you get that special, sweet hot water back, you definitely don't want to proceed through this once again. Here are a few ways to keep the Honeywell control device happy:

  • Keep the area clean : Don't shop gasoline cans, color thinners, or oily rags anywhere close to the hot water heater. Actually if the cups are sealed, small amounts of vapor can escape and trigger the sensor.
  • View the cleaning items : If you're mopping the floor within the utility room with bleach or even ammonia, try to keep the door open up or use the fan.
  • Airflow is definitely key : Make sure the base of the water heater isn't obstructed by boxes or even clutter. The sensor requires a bit associated with airflow to work correctly, and if it's buried under the pile of washing, it may throw the false error.
  • Dusting : Every once within a while, whenever you're doing your own deep cleaning, consider a vacuum attachment or a can of compressed surroundings and clean about the base associated with the water heater where the sensor sits. Preventing dust buildup go a lengthy way in staying away from "nuisance" trips.

When to call a professional

I'm all for conserving money and fixing things myself, but there's a limitation. If you carry out the flammable vapor sensor lockout reset honeywell and the unit fires upward, but you notice a yellow, sluggish flame instead of a crisp blue one, or if you smell a weird "burning" odor that will isn't just dust, shut it down.

Also, if the lockout happens frequently for no apparent reason, there may be a more severe issue with the combustion chamber or the gas pressure. At that point, it's worth the money to have the licensed plumber or even HVAC tech take a look. They will have the various tools to check for actual gas leaks which you may not be able to smell.

At the finish of the time, the Honeywell flammable vapor sensor is usually a bit of the "nanny" for your hot water heater. It's annoying in order to stops a person from doing exactly what you want, but it's only carrying it out because it desires to make sure that your home stays in one piece. Most of the time, that quick knob-rotation trick can get a person back in company and you may get back in order to your morning schedule.
