Note: You can also read how to fix Honeywell hot water heater status light blinking 7 times.
1. Pilot Not Lighting
There are several reasons behind the no blink on the Honeywell Status light. The malfunctioning of the pilot is the major one among them.
A pilot is an essential element of any water heater that connects the burner to the gas valve. It ensures a constant flame to light the burner.
Now if the pilot isn’t lighting the burner, the water will not heat. So, as for the first step, you have to check whether there is light on the pilot. Simply remove the front cover panel and look through a short glass to view the pilot assembly.
If there is no light, be sure dirt and debris have accumulated on the pilot assembly that is preventing lighting the burner.
How To Fix:
First, inspect the pilot. Check and clean out the debris from the tube using a needle or this type of object. It will ensure a fluent gas flow.
After cleaning, reassemble the pilot assembly. Now relight the pilot following the below section.
How To Relight The Pilot On Honeywell Gas Water Heater
Just follow the below few simple steps to relight the pilot with Honeywell Gas Control Valve:
Step #1: Start by turning off the gas control knob to the Off position. Leave it for 10-15 minutes to clear any remaining unburned gas from the air.
Step #2: After that time, set the control knob to the pilot position. Hold down the knob in this position.
Step #3: While holding the knob, press the piezo igniter button at the same time. Keep pressing both buttons until the status light starts blinking.
Step #4: Take a look at the viewport to see if the pilot light comes on. If yes, release the valve and set the knob to your desired temperature setting.
If the pilot light after 90 seconds but the status light will not blink, verify all the wiring from the control valves is in good working condition. Take the help of an electrician to repair the damaged wiring issue.
2. Heater Igniter Not Sparking
After resolving the pilot issue and there is still no blinking on the status light, a bad igniter or malfunctions from the igniter is the second suspect. When you click on the igniter, there should be a tiny spark happening inside of the pilot.
If there is no spark, be sure it is not getting the voltage. Accept this, there may have a few factors behind the malfunctioning of the igniter. For instance:
- Corroded igniter terminal.
- Worn out spark wire.
- Accumulated dust on the spark rod.
- Improper installation of the spark rod and the pilot head.
- Or, the defective spark electrode itself.
Follow the below instruction to resolve the above igniter issues:
How To Fix:
First up, you have to check the wiring connection of the igniter. Make sure the white igniter is snugly inserted into the white or orange connector.
Then, click on the igniter multiple times and look for a spark. If no spark is coming, check the igniter connection for any corrosion. If needed, rub the connection with sandpaper. Also, it should not touch the metal pilot tube and manifold tube.
Now, check the spark wire and ensure it is grounded properly. Blow out the accumulated dirt from the spark button with compressed air.
If still, there is no spark, inspect the spark electrode visually. You need to replace the bent or damaged electrode with the help of a qualified contractor.
After doing all the above, reassemble the heater and relight the pilot. The no status light issue on your Honeywell water heater gas control valve should be solved.
3. Interruption In The Gas Supply
The status light on the gas control valve will not blink if there is an interruption in the gas supply to your water heater. Due to insufficient fuel supply, the pilot fails to heat the thermocouple. Consequently, the pilot won’t light and the status light will not blink.
Anyway, note down some possible reasons behind the interruption in the fuel supply:
- Air in the gas line.
- The gas shut-off valve is not opened all the way.
- Kinked flex tube
How To Fix:
Follow the below few phases to fix the gas supply issue:
Phase #1: Check For Air In The Gas Line
As for the first step, check to see if there is air in the gas line. If so, simply bleeding the air from the line will resolve the issue.
To do so, set the control knob to the Off position and wait for 5 to 10 minutes. It will purge the air from the gas line.
Phase #2: Check For Kinked Flex Tube
Inspect the flex tube to test whether it is kinked from any portion. If so, simply straighten the kinked tube.
Phase #3: Measure the gas pressure of your water heater
Aside from all the above actions, you have to ensure proper gas pressure in your water. Take a pressure gauge and measure the gas pressure.
If you have a natural gas-operated water heater, the pressure reading will be in between a 5-8” water column. In case the reading is not in this range, contact your local gas supplier.
4. Faulty Gas Control Valve’s Electrical Connections
If the Honeywell water heater status light doesn’t blink but the pilot lights, there may have a defective wiring connection with the gas control valve. You will see two black connectors on the gas control valve.
Due to a loose connection of the connector, the red status light will not blink. Sometimes, faulty electrical wiring connectors to the thermocouple, igniter, and thermal switch create a problem.
Here are the needed steps to resolve this connection issue:
How To Fix:
First up, locate the gas control valve. Remove the two connectors of red and white wires from the gas control valve. But make sure you’re not pulling it.
Wait for a while and look for any corrosion on the electrical connection. Remove the debris and reinsert the connectors firmly.
Now carefully detach each of the electrical connectors to the gas control valve. Check out any corrosion in the connections.
Then, insert the connectors again and ensure they are fully inserted and tight. Now, light the pilot using the instructions and check the status light.
5. Tripped Heater Thermal Switch
A thermal switch is a safety device on a water heater. Tripping this safety component is one of the most common scenarios among water heater owners. Due to this, the status light will not blink.
There are several factors for continuously tripping the thermal switch. That includes:
- Blocked vents or insufficient air supply.
- Loose or damaged wiring to the switch.
- Presence of flammable vapors near the unit.
The below guidelines will help to fix the tripped switch issue. Here you go:
How To Fix:
First up, turn off the power to your water heater. Let it be cool. Now inspect the vents of the heater. Clean out clogged debris from the vents using a vent cleaning brush and make them blockage-free.
Also, make sure there are no flammable vapor-creating objects like paint, or gasoline nearby the heater.
Now look for loose wiring to the switch, which is leading the switch to trip unexpectedly. Tighten all the wiring connections.
Finally, you have to reset the tripped thermal switch to get back the element function again.
You will find a small reset button in the center of the thermal switch that is shown in the above picture. Press the button firmly. When done, connect the outer door and check the status light.
6. Clogged Base-in-filter & Arrestor
In most cases, the status light doesn’t blink due to inadequate air supply. Higher chances are base-ring filters or the flame arrestor is blocked by carbon dust and debris, creating combustion issues in the heater.
A lack of combustion air, there creates carbon monoxide in a greater amount which blows out the pilot. As a result, the status light will not blink.
How To Fix:
- Inspect the base-ring filter and the flame arrestor to look for any dirt and debris.
- Take a brush-attached vacuum cleaner to clean out the clogged dust or lint.
- Move the brush back and forth and clean the base area properly.
- Then, clean out the flame arrestor using a household brush. When all is done, the status should start blinking.
7. Defective Heater Thermopile
Last but not least, a bad thermopile is one of the major reasons behind the Honeywell hot water heater status light-off issue. The thermopile unit controller of the water heater converts thermal energy into electrical energy.
The problem starts with this element when there has a limited voltage supply. Basically, thermopile in an open circuit test reads 650 to 850 millivolts. But when it reads below 400 millivolts, be sure the thermopile is faulty, and it needs replacement.
Anyway, the process to test your own thermopile is relatively simple. Here you go:
How To Test Thermopile On Water Heater
To test the thermopile, you just need a multi-meter to read the millivolts. Follow the below instructions:
Step #1: First up, shut off the gas shut-off valve. Remove the front access panel of your water heater.
Step #2: Disconnect the wiring connector of the thermopile from the gas control.
Step #3: Now set your multi-meter to read the voltage. Attach the red positive lead to the red thermopile wire. Also, connect the black lead to the white wire.
Step #4: Then, relight the pilot and hold down the gas control’s thermostat knob once it is light.
Step #5: Keep holding the knob until the maximum voltage is reached. If you see below 400 millivolts, be sure it is defective. Replace the bad thermopile with the help of the technician.
How do I reset my Honeywell water heater?
You can reset your Honeywell Water Heater in some simple ways. First, make sure that the pilot is turned on. Then switch the dial to “very hot” for 10 seconds. After that, switch to “hot” for 10 seconds and to “pilot” for 10 seconds.
Why does my Honeywell water heater keep shutting off?
A defective thermocouple is the root reason for a water heater keeps turning off issue. Either it is dirty or damaged in some way. Also, dirty pilot tubes, faulty gas valves, and clogged air vents are other possible reasons behind this.
Why does my water heater pilot light keep going out?
If the heater pilot light keeps going out, be sure there is a faulty, misaligned, dirty, or damaged thermocouple responsible for this. As it is a safety device, it prevents turning on the gas valve if it gets defects.
