Dyna-Glo Heater Troubleshooting Guide

Possible cause: Dead igniter batteries

Replace AA or C batteries in the igniter compartment. Kerosene heaters use battery-powered igniters.

Possible cause: Clogged or worn wick (kerosene)

If the wick is blackened or hardened, replace it. A new wick needs 60 minutes to soak before lighting.

Possible cause: No gas supply (propane/NG)

Check that the propane tank valve is open and the tank isn't empty. For natural gas, verify the shutoff valve is open.

Possible cause: Faulty piezo igniter (propane/NG)

If you don't hear a click when pressing the igniter, the piezo crystal is worn. Replace the igniter or light the pilot manually with a long match.

Possible cause: Air in the fuel line (forced air)

After refueling, it may take 2-3 ignition attempts to purge air from the fuel line. This is normal on first startup of the season.

Possible cause: Bad thermocouple

The #1 cause. The thermocouple is a safety sensor that detects the pilot flame. If it's worn, it tells the gas valve to shut off. Replace the thermocouple — it's a $10-15 part and a 10-minute job.

Possible cause: Thermocouple not positioned correctly

The tip of the thermocouple must sit directly in the pilot flame. If it was bumped during cleaning, reposition it so the flame wraps around the tip.

Possible cause: Oxygen Depletion Sensor (ODS) triggered

Vent-free heaters have an ODS that shuts off gas if oxygen levels drop. Open a window or door to improve ventilation. If the heater keeps tripping in a large room, the ODS pilot assembly may need cleaning or replacement.

Possible cause: Dirty pilot orifice

Dust or debris in the pilot orifice causes a weak pilot flame that can't heat the thermocouple. Clean with compressed air — never use a pin or wire.

Possible cause: Low propane tank

When a propane tank is nearly empty, pressure drops and the heater may not sustain a flame. Check tank weight or try a full tank.

Possible cause: Flame failure detected

E1 means the heater tried to ignite but the photocell didn't detect a flame. Check the fuel supply, clean the fuel filter, and inspect the igniter plug for carbon buildup.

Possible cause: Dirty photocell

The photocell (cad cell) is a sensor that "sees" the flame. Wipe it clean with a soft cloth. If it's cracked or discolored, replace it.

Possible cause: Clogged fuel nozzle

A partially clogged nozzle causes poor atomization and inconsistent ignition. Replace the nozzle — they're inexpensive and should be changed every 1-2 seasons.

Possible cause: Bad fuel

Old kerosene (6+ months) or water-contaminated fuel causes ignition problems. Drain and refill with fresh 1-K grade kerosene.

Possible cause: Wick set too high (kerosene)

Lower the wick slightly. The flame should be a blue ring with small orange tips. A tall yellow flame means the wick is too high.

Possible cause: Worn or dirty wick (kerosene)

A tarred wick produces yellow flame and smoke. Perform a dry burn or replace the wick.

Possible cause: Low-quality kerosene

Red-dyed kerosene (K-2) burns dirtier than clear 1-K grade. Always use 1-K kerosene for indoor heaters.

Possible cause: Insufficient air supply (propane)

Blue flame wall heaters need room air for clean combustion. Make sure the air shutter is adjusted correctly per the manual.

Possible cause: New wick not fully soaked

A new wick that hasn't soaked long enough produces a strong smell during the first burn. Let it soak 60+ minutes.

Possible cause: Wick set too low

If the wick is too low, incomplete combustion produces kerosene fumes. Raise the wick until the flame is a full blue ring.

Possible cause: Startup/shutdown smell (normal)

All kerosene heaters produce some odor during lighting and extinguishing. This is normal. Ventilate the room briefly.

Possible cause: Gas leak (propane/NG)

If you smell gas from a propane or natural gas heater when it's not running, shut off the gas supply immediately and check all connections with soapy water for bubbles. Do not operate until the leak is fixed.

Possible cause: Thermostat set too low

Turn the thermostat to its highest setting and wait 5 minutes. If the fan runs but no heat comes out, the issue is the heating element or wiring.

Possible cause: Tripped circuit breaker

Electric garage heaters draw significant amperage. Check that the breaker hasn't tripped and that the circuit is rated for the heater's wattage (30A for 7500W, 50A for 10000W).

Possible cause: Faulty heating element

If the fan runs but air is cold, the heating element may be burned out. Replacement elements are available — always disconnect power before servicing.

Possible cause: Wiring issue

These are 240V hardwired heaters. If the heater was recently installed, verify wiring matches the diagram in the manual. A miswired heater may run the fan without engaging the element.
