Common Heat & Glo Issues We Fix
These are the most frequent Heat & Glo fireplace problems GEM diagnoses and repairs in homes throughout the northwest Chicago suburbs.
Pilot light won't stay lit
Heat & Glo units use a thermopile to generate the voltage that powers the IntelliFire ignition system. A degraded thermopile produces insufficient voltage, causing the pilot to extinguish or the main burner to fail to open.
IntelliFire ignition system failures
The IntelliFire IPI (Intermittent Pilot Ignition) system is common in Heat & Glo gas fireplaces. Failures include no spark at startup, the system cycling without igniting, or the unit locking out after repeated failed ignition attempts.
Burner not lighting fully or uneven flames
Partial ignition or uneven flame patterns typically indicate a dirty burner, blocked ports, or low gas pressure. A full burner cleaning and gas pressure check resolves most cases.
Blower or fan not working or noisy
Heat & Glo units with circulation fans develop bearing wear over time, producing rattling or grinding noise. A failed fan motor or thermal switch can also cause the blower to stop running entirely.
Remote and wall switch problems
Receiver modules, wall switch wiring, and remote batteries are common failure points. We diagnose the full control circuit to identify whether the issue is the remote, receiver, or wiring.
Sooty glass
Black soot deposits on the glass indicate incomplete combustion — often caused by a dirty burner, incorrect air shutter setting, or a vent restriction. Cleaning the glass without addressing the root cause will result in rapid re-sooting.
Gas odor concerns
Any gas odor near a fireplace should be treated as urgent. We check valve seating, pilot assembly connections, and all gas fittings for leaks before any other diagnostic work.
Clicking without ignition
Continuous clicking without a flame indicates the igniter is sparking but the pilot is not lighting — usually a gas supply issue, a clogged pilot orifice, or a failed igniter electrode.
Our Service Process
Full ignition system diagnostic
We test thermopile output voltage, the IPI module, spark electrode, and control wiring to identify the specific failure point before ordering any parts.
Gas pressure check
We verify manifold and inlet gas pressure is within the manufacturer's specified range. Low or high pressure causes ignition failures and uneven flames that look like component failures but are actually supply issues.
Burner, pilot assembly, and glass cleaning
We clean the burner ports, pilot orifice, and thermocouple tip, and remove soot deposits from the glass. Dirty components cause most of the symptoms homeowners attribute to part failures.
Parts replacement with compatible components
We replace failed components with compatible parts and confirm fit and function before completing the job.
Safety test and written report
We test the full ignition sequence, verify the flame pattern, and confirm there are no gas leaks before leaving. A written report documents the work performed.
Annual Service — Before Every Heating Season
Gas fireplaces should be inspected and serviced once a year, ideally before the first use of the heating season. An annual tune-up catches thermopile wear, dirty pilots, and venting issues before they cause a failure on a cold night.
Gas fireplace inspection serviceIf Your Unit Is Beyond Repair
Older Heat & Glo units with failed heat exchangers, cracked fireboxes, or discontinued parts may not be worth repairing. GEM installs new gas log systems and fireplace inserts as replacement options.
