Understanding the Problem
What this model is and why problems occur: The FGHB2844LPG is a Frigidaire freestanding gas range configured for liquid propane (LPG). Most service calls for this model relate to ignition (burner or oven), weak or no flame, oven not reaching set temperature, persistent clicking, or gas odor. Below are practical diagnostic steps and repair instructions for the most common failures. 1) Burners won't light or spark but you hear clicking - Check first: Are the burner caps and crowns seated correctly and clean? Moisture or food debris commonly prevents sparking or flame ignition. - Diagnostic steps: 1. Turn a burner on and watch the igniter (electrode) where the spark should occur. If you don’t see a spark, the electrode, wiring, or spark module may be faulty. 2. If you see sparks but the gas won’t light, ensure gas supply is on and the burner ports aren’t clogged. 3. If a burner lights but clicks continuously, the electrode may be wet/damaged or the spark module is failing. - How to fix: 1. Turn off power (unplug range) and ensure the gas is off at the appliance (and house valve if working on gas lines). 2. Remove burner grates, caps, and crowns; clean ports with a soft brush or thin wire and ensure caps sit flat. 3. Dry and inspect the electrode for cracks or grease. Replace the electrode if the ceramic is broken or the tip is corroded. 4. If electrode looks OK, test/replace the spark module (located behind control panel). Verify module gets 120VAC when you push the knob to ignite (use a multimeter if comfortable). 2) One or more burners light weakly or flame is low - Diagnostic steps: 1. Confirm propane supply pressure and that the correct orifice is installed for LPG. LPG ranges need the correct LP orifices and pressure regulator/LP conversion kit installed. 2. Inspect burner ports for partial blockage and clean. 3. Check regulator adjustment and manifold pressure (a pro should check pressure with proper tools). - How to fix: 1. Clean ports and burner parts. Reassemble and test. 2. If still low, confirm LP conversion kit was installed (correct orifices and regulator spring). Replace orifices if incorrect or damaged. 3. If regulator is suspected, replace with OEM regulator matched to FGHB2844LPG. 3) Oven won't light, glows weakly, or takes very long to heat - Diagnostic steps: 1. Set oven to bake and watch the bake igniter (hot-surface igniter). It should begin to glow bright orange within 30–90 seconds and then gas valve will open and flame will light. If the igniter never glows, the igniter or its wiring is defective. 2. If igniter glows but you never get a flame, the igniter may be drawing insufficient current to open the gas safety valve (igniter aging). A weak glowing igniter commonly means replace it. 3. Check oven temperature with an independent oven thermometer. If oven off by >25°F, check oven sensor resistance (typically ~1100 ohms at room temp; verify spec in tech sheet). - How to fix: 1. Disconnect power and gas. Remove lower oven access panel to access igniter. Unplug harness from igniter, remove mounting screws and replace igniter with OEM replacement. Do not touch new igniter surface with bare hands (oils shorten life). 2. If temperature is off, test oven sensor with a multimeter. Replace sensor if resistance is out of spec or fluctuates. 4) Persistent clicking after ignition or while burner off - Diagnostic steps: 1. Check for moisture: spill or cleaning solution can leave moisture in switch/igniter area—dry thoroughly and test later. 2. If clicking remains, inspect the electrode tip and alignment—if tip too far from cap, spark may continue. 3. If electrode and wiring OK, suspect the spark/ignition module or a faulty infinite switch or control board. - How to fix: 1. Dry and clean. Re-seat burner parts. Replace electrode if damaged. 2. If problem persists, remove control panel and test/replace the spark module. 5) Smell of gas - Immediate steps: 1. Stop using the appliance. Do not light matches or turn electrical devices on/off. 2. Open windows, evacuate house if smell is strong, and call your gas provider or emergency services. For any leak, a qualified gas technician should perform repairs. General replacement tips (safe step-by-step for common parts): - Always disconnect electrical power (unplug or shut off breaker) and turn off gas at the appliance and house valve before servicing gas components. - Use the exact replacement part for FGHB2844LPG – do not substitute parts that are not specified for LPG conversion. - Keep a soap/water solution for leak checks on any reconnected gas fittings — apply and look for bubbles and retighten as needed. - After any gas work, do a leak test and verify proper ignition and flame characteristics on all burners and oven. Safety note: Working on gas appliances involves risk of gas leaks, explosion, and carbon monoxide. If you are not fully comfortable or certified to work on gas systems, or if you detect a gas leak, stop and hire a qualified appliance/gas technician.
Common Symptoms
Burners won’t spark or ignite, continuous clicking, weak burner flame, oven won’t light or reaches temperature slowly, uneven oven temperature, gas smell.
Common Causes
- Clogged or misaligned burner ports or caps
- Failed electrode/pilot igniter or spark module
- Aging/weak bake (hot surface) igniter or faulty oven sensor

Helpful Repair Tip
To confirm a failing bake igniter: set oven to Bake and watch. If the igniter glows dim orange but the oven never lights (or takes >90 seconds), the igniter is almost always the culprit and should be replaced.
Frequently Asked Questions
Is it safe to replace the oven igniter myself?
Yes, if you are comfortable with basic appliance repair: disconnect the range from power and gas, remove the lower access panel, unplug and unmount the igniter, and install the OEM replacement. Avoid touching the new igniter surface, tighten screws, reconnect, restore power and gas, and test. If you are not confident or if gas fittings must be disturbed, hire a qualified technician.
Why does my burner keep clicking even after the burner lights?
Common causes are a wet or contaminated electrode, an electrode tip that’s misaligned relative to the burner cap, or a failing spark module that continues to send spark signals. Clean and dry the electrode area, ensure caps are seated correctly, and if clicking continues, replace the electrode or ignition module.
