I have the same Hamilton garage heater that is doing the same thing as the person that posted in May. This is actually the second one that I have had that did this. I called the service line with the first one and they ran through a bunch of stuff with me and basically told me that they would not ship a replacement part since they can't verify installation. They told me my 30 yr old house may have not been grounded properly. I returned the unit to home depot and got a new one. Now this one has sat for 9 months and I have re-installed in in a new home and it is doing the same thing that the person describes. glows, fires, and poofs out repeatedly until system lock out. Any ideas what i may be able to do about this....again? Both heaters worked perfectly until they started doing this.

Any help is appreciated.

Just want to say don't ever buy a Hamilton Garage Heater!!!! I posted on this forum looking for advise n what may be wrong. I have called Hamilton and the first guy ran me through a few possibilities and they didn't fix the heater. I called back and got John, which was the person i got two years ago who told me that it wasn't grounded right. He told me the problem was that i put a plug on the end instead of hard wiring it. I thought a connection is a connection. I was then honest with John and told him that this was the second unit that I have had that did the same exact thing after 2 years and asked if there was issues with the unit. He said no and asked what i did to fix the first one? I promptly said that I returned it 2 years later and exchanged it for a new one...brought it home hoked it up and it worked perfectly. The only thing I changed was the unit! I have now moved it to a new home two years later after sitting for a year it is now doing the same thing as the first one. He insists the problem is me or my house and not the second unit in a row to do this.

I am going to buy a Mr Heater unit this weekend and will post if I am wrong that Hamilton is shit!!!

DO NOT BUY HAMILTON HEATING PRODUCTS!!!!!!

Most, if not all 110-120 volt appliances must be on a dedicated line. This means nothing else on the same properly grounded circuit protected by a 15 amp circuit breaker or time delayed fuse. #12gauge house wire is preferred.
Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:

1. Thermostat calls for heat.

2. Draft inducer motor starts.

3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes.

4. Draft inducer(Power Venter) runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas.

Solution:You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem.

Since this is an old post I will not post how to troubleshoot it. If you still have trouble, email or pm me and I will help you. I know what I'm doing, worked on furnaces, boilers all kinds of HVAC equipment for almost 25 years as a service tech and am now an HVAC/R instructor.
