Hot air blower heater constantly goes on and off couple of times every second once it reaches its set temperature. It flickers. Anybody same problem?

This is what you would expect to see. The drive current to generate the heat is turned on an off as the temperature of the gas is regulated to a constant value. The soldering iron drive will show comparable behavior.

I had the same problem and was told by their customer service that a bad batch of thermostats was installed in some units. They are sending me a new thermostat, which i guess i will install myself. I also have had two issues now with the on/off switch not working properly. I am sorry I bought this unit.

I have incurred the same issue. What has worked for me is before turning unit on, make sure the heater and temp control are off. Once the fan starts moving, then turn on the heat and temp.

Mine turns on just fine with no flickering, but mine is in our heated house. Typically the flickering is caused from using a fluorescent type fixture in a lower air temperature (below 35-40). The ballasts on most of these you find in HD or Lowes aren't made to work in lower temperatures and they will flicker until they warm up.

Just got one on Tuesday 2/9/10. Same buzzing problem, but found out it was getting some type of interference from our space heater. Look for something that may be causing the same thing in your home. We turned off the space heater and now we're colder, but NO BUZZING. Hope this helps!

I had mine plugged in for a few months - only using it occasionally - and one night when I wasn't using it, started flashing red in the middle of the night - it didn't turn the heat on while it did this. It didn't stop when I used the control so I unplugged it and replugged it in and it's been fine. Nothing in the manual about that. If it does it again I will call the manufacture.

So, mine has started doing the same thing. It has been months since I replaced mine and it is just now flickering. My guess is that the bulb is just cheaply made and not a true Factory bulb. For as cheap as the bulb was I wouldn't expect much over a year out of it but the flickering is pretty annoying. I don't know of a fix other than getting a new bulb.

That problem has not occurred on my heater and I always use it on low setting. As someone else suggested, clean the pilot to get rid of dust.

Hi, Haven't had ours for long enough to have any problems. However, knowing what little I know about electrical heating elements, if it's making noise that's probably not a good sign. Would take the time to send it in either for repair or replacement. These aren't complicated devices, but the potential for fire is always lurking the background. Don't want to overkill, but wouldn't take any chances... Jay Miller

My unit has not over heated. If its really hot, I would think it is a defective unit.

I believe that means it's overheated and has tripped an internal safety breaker switch. It should reset itself when it cools down. Make sure there is nothing obstructing air to the unit and that the blower fan is operating ok.

I have had no problems like that at all.It has never gotten up to temp and come on every 5 seconds.I love this heater and it maintains the set temp,no problems.

I have not had any problems yet. But I think the unit is not starting as fast as it did at first. But it is still heating as it should.

Beverly, you didn't state your model or how old the unit, but one common weak link is the on/off switch may be faulty, the second primary failure mode would be the heater coil/thermostat and would generally be cheaper to buy a new one than try and fix. If you have a handyman around he should be able to check out the on/off switch.

Mine works great. You must have already tried adjusting the thermostat on the small electrical box that is attached to the fan. Actually my fan turns on at the right time, but fails to turn off soon enough for my taste. This is because the hysteresis is a bit much. I hope this helps, stay cool.

Hi, Mine first did that when it was first installed. The temp was set to high. I unplugged the unit and not turn it back on until the next morning and it has been great since then.

Sounds like a defect. I have never had that problem. The bottom element always turns on and heats up for me.
