A close look needs to be taken at the problem to find a lasting solution to it.
With the information provided here, you can rest assured that troubleshooting your gas fireplace electronic ignition wouldn’t be a headache.
For a lot of homeowners who use gas fireplaces, problems affecting normal functioning are likely to come up.
These range from dead batteries, gas leaks, burner failure from pet hair and dander, cloudy gas, the air in the gas line, and ignition problems among others.
Gas Fireplace Electronic Ignition Troubleshooting
All of these issues affect normal functioning and have to be resolved before they worsen. Here, we’re looking at one of them which is; a faulty electronic ignition.
What are the causes? How does one troubleshoot such? Can it be repaired?
All these are important questions that need to be answered in the best way possible.
How a Gas Fireplace Igniter Works
The successful ignition of fire rests on an igniter.
This is also known as the direct ignition system. This device or fireplace component holds a spark ignitor which consists of a simple electrode responsible for bringing about the spark required.
The strong spark generated is brought about by the voltage supplied by a control module. Whenever you turn on the controls, the resulting spark ignites the gas released by the fireplace burner.
When this happens, a flame rectifier, also a part of the fireplace igniter is heated.
Such heating of the flame rectifier is necessary to serve as a sensor that relays signals to the control module. The heat is a sign that fire is present.
Having extinguished the flame, such signal is no longer relayed to the control module, thus activating a closure of the gas valve.
This intricate function of the gas fireplace igniter makes it very crucial for flame lighting purposes. However, gas fireplace igniters are no longer common due to more recent fireplace designs having alternative ignitors.
Gas Fireplace Ignition Problems Can be Varied
When it comes to the workings of an electronic gas fireplace ignition, there are several factors to consider. As such when problems occur, all sorts of variables are involved in terms of troubleshooting.
So, what are these problems like?
These could range from a pilot not working, noise but no spark at the pilot burner, and also a pilot light not sparking at all. These are only a few scenarios that point to a malfunctioning gas fireplace electronic ignition.
Without further ado, let’s get to the basics of what troubleshooting entails.
Symptoms, Problems, and Test Solutions
These are the key areas our discussions will focus on. First off, you’ll need to consider the symptoms. These are malfunctions that prevent the gas fireplace from coming on.
You’re likely to find a problem that fits your situation. By following the troubleshooting tips provided, you’re likely to resolve such a problem.
Symptom 1: Pilot Sparks as Usual but Doesn’t Light
Whenever you notice this, it’s a clear sign of malfunction that points to multiple cases such as issues with the gas supply, or a module that isn’t grounded.
The only way to ascertain the causes is by troubleshooting.
What to do
Several actions can be taken to resolve this problem. First, you’ll need to verify that that the ball valve on the incoming gas line is in the “Open” position.
Secondly, confirm that inlet pressure reading is within range of acceptable limits. Ensure that inlet pressure doesn’t exceed 14” W.C.
If all is working properly, the problem may lie in a module that isn’t grounded.
To find out, closely examine the valve and pilot assemblies to be certain they’re grounded to the metal chassis of your log set or fireplace.
Symptom 2: Sparks Continue and Pilot Lights but Main Burner doesn’t do the Same
When this is observed, many reasons can be attributed to it.
These include exhaustion of propane gas, contaminated sensor rod, loose connection in sensor rod, damaged pilot, poor grounding between pilot assembly and gas valve.
What to do
There are many actions to take when it comes to troubleshooting the problem.
One way to find out if it’s out of propane is by checking. Have it filled up and start as usual.
When a damaged dirty sensor rod or damaged pilot is suspected, you’ll need to perform the following troubleshooting actions;
Get the sensor rod cleaned using emery cloth. This helps get rid of accumulated contamination on the sensor rod.
Now, get your multimeter and test for continuity. Of course, the right settings will need to be set (that is, ohms set at the lowest range).
In the case of poor flame rectification, examine the flame to ensure it’s engulfing the sensor rod. Also, check to make sure the pilot orifice is properly installed and the inlet specifications align with those provided in the manual.
Another possible problem is poor grounding between the gas valve and pilot assembly. To troubleshoot, assess the grip or hold of the wire harness to the module. This should be firm enough.
What more? Check the ceramic insulator. This is located around the sensor rod.
When loose, cracked, or damaged, it should be replaced.
Symptom 3: Pilot Light Stops Sparking or Remains Lit without Burner Coming On
Here, there are two scenarios; a pilot light that stops sparking, or one that works but the burner doesn’t come on while the pilot light stays lit.
This could be due to one or more problems ranging from a faulty wiring harness, wiring or connection problem, and the module or valve.
What to do
If you suspect the wiring or connection to be the problem, you can troubleshoot such by inspecting all wires. Here, you’ll need to ensure they’re tightly connected. Plus, they should be installed as specified in the manual.
When the module or valve is suspected to have issues, you’ll need to have such tested.
An appropriate tool is a multimeter. Have the multimeter turned to “DC.” With this done, the red lead from the multimeter is placed on the screw located on the terminal block being examined.
With the black lead of the multimeter, have it placed on the valve body which is ground. When a “zero” reading is obtained, the module or valve may have issues.
For the wiring harness component, you’ll need to have it closely inspected. This should be tightly connected to the module. Plus, all wires should be connected in the right order.
Symptom 4: Pilot Doesn’t Light and also Makes Noise Without Spark at Pilot Burner
If this sounds similar to the problem you’re facing, it could be due to some reasons such as a loose connection, wiring, and an incorrect igniter gap. So, how do you go about troubleshooting such problems? It’s easy!
For wiring problems, you’ll first need to ensure that both the igniter and sensor wires are connected to the proper terminals. In the case of a loose connection, check that there are no loose connections whatsoever.
Also, ensure there is no electrical shorting in wiring. When the igniter spark gap is deemed to be incorrect, make the necessary adjustments.
When Gas Igniter Doesn’t Give Off Sparks
It has been necessary to discuss the functions of a gas fireplace igniter because such knowledge helps with a better understanding of the topic being considered.
When a gas fireplace igniter doesn’t give off any sparks, such problems need to be traced.
Remember we said that sparks are produced or generated from an electrode that receives voltage from a control module. Now, the absence of sparks in your fireplace igniter is likely due to zero relay in voltage from the control module.
This is only a strong possibility and not a definite spark.
Other issues may be discovered as being the reason for the absence of sparks in your gas fireplace igniter. Whatever the case is, an in-depth assessment has to be made as to why your igniter isn’t functional.
