SOURCE: heater won't stay on

This product does indeed have a problem with the safety switch, that is only supposed to kick in when the unit is turned over. I had a total of 3 units sent to me from Kaz. Each time the unit would work for a short time, then slowly begin to turn off and on. I finally decided to take the unit apart and look for any obvious problems. There is a weighted swivel that will raise a contact point to turn the unit off in an emergency. The contact points would spark off and on, depositing a black carbon on them until they would no longer allow power to pass through. I cleaned the contacts with a fine finger nail file and bent one of the contact arms inward to make better tension between the contacts. This allowed the unit to stay on for longer periods of time. But even with the thermo-stat turned all the way up, the unit does not stay on long enough to heat the room. In effect, what happens is the contacts will continue to ark, putting black deposits on the contacts until you're back to square one. Apparently the unit also has a thermo-stat related problem. I'm sending the unit back again (they only made me send the power cord last time), but will insist on a different model this time. Good Luck

SOURCE: Heater will not stay light

90% of the time, this problem is caused by either a clogged gas orifice on the pilot light's gas line, or by dust/debris in the pilot air intake, as stated by tradesman1. Start by blowing compressed air through the pilot air intake, both directions. If that doesn't solve the problem, remove the pilot assembly, then the pilot orifice, and blow compressed air backwards through the small orifice. The bottom line is that anything that causes the pilot flame to reduce in size will trigger the oxygen depletion system and that will result in the unit shutting itself off. This is a safety measure. Other possible causes: insufficient gas pressure to the unit, high altitude, defective thermocouple.

SOURCE: when heater works electric line trip off

You're drawing more amps than your line is equipped for. Rather than modifying your electric, unplug something on the same line to reduce the current draw.

I have a toastmaster model 2517 space heater. it comes on for a few minutes and then shuts off and then in a few minutes then comes back on. is that normal for that model? if not,how do I fix it?

it sounds like it is turning off when it reaches the temperature setting you have it at. turn it a little higher and see if it stays on longer.

How do I get the heater to stay on?

What type of heater? make/model should always be given so we have a fair chance of giving a good answer. In light of a lack of information, I must assume it is a portable electric heater.

Try adjusting the thermostat/temp control and see if it turns on. If it turns on but shuts off after a a minute, you may have it to close to other objects or a wall. The heater output can be blocked or recycled back into the heater which will cause the heater temp control to warm up fast and shut off.

Iaqualink heater shuts down after a few minutes

Does the heater continue to fire if you run it in service mode? If so it probably is an Aqualink issue. I'd call the factory on that one and they should be able to get a rep or authorized service company to see what's happening.

If the heater is also shutting off in service mode the problem may be in the bypass ***'y. This is not an uncommon issue with the Minimax. Too much water is bypassing the heater and the water that does get in is staying there too long, triggering the high limit switch which will shut down the heater.

The heater comes on for a few seconds then shuts off but once or twice a week it comes on and operates like a normal heater

Mine does the same thing. I have a gas heater. It will fire up- run for less then a minute then shut off. then 2 minutes later does the same thing. I'm thinking of going with a differeny brand because this is using a lot of gas evertime it fires up just for a minute. if I turn it up it stays on till it reaches the temp then does that on off thing again. i think it is just the so called "feature" Honeywell is claiming to maintain the temp in our home, not realizing it is wasting your gas or electricity.

All of these space heaters have thermal protection units in them. They are safety that shuts the unit down if it starts to overheat.If your fan is operating, then it sounds like the thermal protection circuit is faulty, and you'll need to contact Lasko for a replacement. These units do not have parts that can be purchased due to their UL compliance. Check the fan though, it might be obstructed. I have seen that more than once....Rob

Make sure that the thermocouple is well into the flame. Check to make sure the other end is secure into the gas valve. Check for any poor connection both gas and electric. If the LP cylinder is icing up, it is a vaporizing problem and the heater is sucking the available gas out of the cylinder faster than it can vaporize. You will need a larger cylinder.

Unit shuts itself off within a few minutes.

. Try taking a can of compressed air and spray in the vents in the front and the back of the heater. The heater has a sensor that gets dusty and causes it to shutoff to prevent overheating.

The heater should function properly once the dust is blown off the sensor.

Good luck!
