Sounds like a short circuit/ Or a weak breaker. If there were a fuse in the heater it would not trip the breaker because the circuit would be open with a blown fuse. To check the unit from the plug use an ohm meter and test from each terminal on the plug to the half rounded ground. You should have no reading at this point. If you do there is a short in the unit.

E3 error on LIfesmart heater

Even after replacing thermostat and motherboard offered from company, my heater would trigger e3 error code and shut off. After several (maybe 100!) different attempts to plug in and operate, here is what worked for me!
Depress the power button on the heater while plugging in to wall circuit. Continuously depress power button. It will run through a test cycle and attempt to start. Keep depressing the power button as the heater tries to start, then shuts down with e3 error. While the power button is still depressed, unplug the unit from the wall. When I plug back in the wall the E3 error is gone. Good luck

My Rinnai dynamo has gone from being 'non smelly' to being quite high in emissions when in use.

Since your heater is a Flue-Less Or Vent-free (as it's called in here in the US), I suspect it needs a thorough interior cleaning. This generally is the cause of "smelly" heater. Keep in mind, flue-less heaters use interior air for combustion. So, whatever is floating in the household air (dust, lint, pet air, etc) eventually gets into the heater and clogs it up, causing incomplete combustion and odors. In addition, fresh paint odors are made worse by the heater. Rug or carpet cleaning products will do the same thing. Even days after they are cleaned. Paint smells may last for a week or more. During these times, the heater should be turned OFF and the house allowed to air out, whenever possible.

All heaters, whether they are flue-less portable heaters like yours or a vented model, should be professionally serviced annually. Usually in the Fall, before firing it up for the Winter.

In case you have misplaced your Owners Manual, I have included a link to it, that you can download and print for future reference.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

I have a customer who has a Rinnai RHFF-551FA heater. She will manually turn it on, walk out of the room, and when she comes back (I don't know how soon she returns to the room) the switch will still be...

Check the mode and temp setting (must be +5 degree than room temp). And wait for minimum 3 minutes. If no heat air starts, check heat sensor with ohms meter. If sensor is good, as you said, the problem with PCB. replace it. Hope helpful?

We had an old 1970s fan heater in the ceiling of the kitchen that was attached to a light switch to turn on/off. We want to attach a light fixture to the ceiling where the heater was and use the same...

Sounds like we need to do some tracing of history over they years:

1.) How long has the heater NOT been used? (Has it been removed?)

2.) Since a heater draws considerable current-- It likely was on a separate circuit.
Could that circuit have been re-wired to some other load in the house?
Or could that circuit have tripped?- or blown a fuse?

3.) Has the switched remained connected to this circuit all this time?
Is the switch still turning on and off the light? (or did I just mis-understand that statement?)

Give us more information, so we can help you further.

Our AC unit is on inside the house but blowing hot air. Outside unit is not on. My husband tried to turn the fan blades on the OS unit and it won't turn. Is the fan motor gone?

It is a strong possibility. Use some oil on the motor.34a4ac9.jpgIt might be the contactorace24b7.jpg
Before he goes messing with anything inside the unit he needs to kill the power. It may be the capacitor, look for a swollen cap45d0615.jpg06e208f.jpg

I have a 220v 100 amp circuit breaker that feeds a sub-panel. The sub-panel has 3 circuits: a)60 amp Heater (unit 1 in house) b)60 amp A/C (unit 2 in house) c) 40 amp for pool equipment. The 100 amp...

your a/c uses the blower motor from the heater to distribute air check for loose wire connections that will raise amperage and also make sure you have the right size wire to each unit 40 amp should have 8 awg(copper) wire and 60 shouldbe 6 awg i think if the wire is to small=heat= higher amperage

LG S36AHP-UD7 Split Air Con. won't turn on.

Generally when an ac trips the main breaker and the breaker its self isn't bad, the compressor is going bad or is bad. To check you will need to do an ohms test on the compressor. If you get a reading of less than infinite, then the compressor is bad. You will need to test every lead going to the compressor which is usually 3 unless you have a crank house heater installed but they are not typical on a small unit. If the compressor has gone bad it is possible the it took the board out as well.

Blower on our house heater will not shut off

Check the limit switch.most look like box with a switch or button.Next to the switch or button it will say auto - on .The button style will run the fan if the button is pulled out.Common problem is the button breaks fans stays on all the time.
Unplug the unit before replacement, fairly straightforward repair, if you question your ability call a professional, as this is a safety device.
