Question about Honeywell HZ519 Baseboard Heater

2 Answers

Powers on, no heat

My heater powers on normally (the lamp in the same outlet even flickers slightly), but no heat. All the indicators in the display appear normal. Sometimes, you can feel the slightest bit of warmth, but that's it. It's only 2 years old--it worked OK for a few weeks this year--then nothing.

Yes--it's plugged in
Yes--it's clean
Yes--it's upright

HELP!! It's getting cold!!

Re: Powers on, no heat

I have this model heater and it quit working as well. I took it apart to find that the plastic bosses that the safety switch mounts/screws to melted and the switch fell into the bottom of the heater rendering the heater useless.
FYI, The safety switch removes power from the heater when the heater is laying on it's front or back incase it gets knocked over while it is on.
This is a serious defect. These heaters should be recalled.

Dimplex dakota heater is working but flame effect is not its led I think not bulbs.

Says you can turn it on and off? Did you knock the switch?

Can I operate the flame effect on the fire without the heat?
All our Optiflame and Opti-myst fires can be operated on a flame-effect only setting, as can the flickering flame effect on our freestanding bar fires.

Is the flame effect expensive to run?
No, to run the flame effect involves powering light bulbs and a small electric motor and in most cases costs no more than a couple of pence an hour. Some of our fires have LED lamps fitted which are even more energy efficient.

Some have bulbs, some have LED.
Example calculations:
Using UK standard average price of electricity of 14p/kWh (source: Energy Saving Trust Feb 2015)
Optiflame LED flame effect only (eg Danesbury) = 0.1p every hour
Optiflame conventional bulb, effect only (eg Cheriton) = 2p every hour
Opti-myst, flame effect only (eg Oakhurst) = 3p every hour
Opti-V single screen = 0.5p every hour
2kW fan heater, on constantly (no thermostat) = 28p every hour

Optiflame lightbulbs for sale. Remove the coals and check for bulbs.

My chauffe air heater will not give off any heat

see this causes and fix it. God bless you
If an appliance that should produce heat does not, inspect the element for breaks or obvious damage. If you don't see any damage, test the element for continuity (see below).
  1. Turn off power to the appliance or device. If the unit is plugged in, unplug it from the electrical receptacle (outlet); if the device is wired into the circuit (such as an oven), turn off the circuit at the electrical service panel.
  2. Disassemble the appliance or device to access the heating element, following the guides in this book for your appliance. Some heating elements, such as plug-in units in electric ovens, are relatively easy to remove (see the Electric Oven Fix-It Guide).
  3. Set the multimeter to RX1 (resistance times 1).
  4. Touch the multimeter probes to each end of the element.
  5. High resistance (kilo-ohms or thousands of ohms) indicates the heating element is okay. A reading of infinite resistance indicates a broken element.
  6. If a heating element is faulty, replace it with one of the exact size, shape, power rating, and resistance.
  7. Reassemble the appliance or device and turn it on or plug it in to test it.

We have a new OFC2400TIF heater. We have set a program which worked for a day. Now the heater will not work on either manual or auto. The display lights are all on, the screen indicates that the heater is...

The heater may need to reset itself. Turn the Master ON/OFF Switch to OFF and unplug the heater from the wall outlet. Wait 12 - 15 minutes and plug the heater back in. Turn the Master ON/OFF Switch to ON and set the controls as you normally would. Hopefully, that 12 - 15 minute timeout allowed the heater to reset itself. If this continues to occur, contact Dimplex Technical Service at

Hope this helps you to further troubleshoot and solve the problem.

Have you checked the outlet that the heater is plugged into, to be sure it's working. Unplug the heater and plug in a lamp. If the lamp doesn't turn on, than the problem is in the wall outlet or the circuit breaker has been tripped. Unplug the lamp, reset the circuit breaker and plug the lamp back in first. If the lamp works and doesn't trip the circuit breaker, unplug it and plug in the heater. If the heater trips it when you turn it on, there's an electrical problem in the heater.

Lowe's & Home Depot stock and sell this heater. See if either has one in stock. If they do, take it to the Customer Service Desk and they'll gladly make you a copy of the Owners Manual from the one in the box,

Hope this helps. Please let me know.

We have wired it in and the hot water works, but the heating doesn't, no even when we go to manual

So you mean the water comes out of the Hot Water outlet, but it is NOT hot? You do not indicate what "IT" is. I presume a hot water heater. If you have a manual, and you follow the troubleshooting procedure, and it still will not work. Then either the device is faulty, and needs to be replaced, or it is wired incorrectly, or a sensor is not connected or faulty, or set wrong. It hasn't got power, the element isn't working, check all elements Resistances. Check Thermostat,is OK, and is set right. Check all wiring again. Try removing the Power, wait 5 minutes and reconnect,perhaps it was just "Hung Up".

Pelonis heater does not heat

Hi, Have you checked to make sure that there is power at the outlet you are plugged into? I have looked up some information on this heater and it is in the top 5 oil filled heaters. I do know this, they are maintainence free. They are sealed and no place to fill will oil as the oil is heated to a certain temperature and not enough to burn the oil, so they never have to be filled. Anyway, check for power, and if you have power, check the cord over for any damage. If you can't find anything, you have a internal problem with the control on this heater. This is something you may want to take in to a appliance repair store and have checked out. There is no fuse to replace, so I would say a problem in the circuitry. There is not much for me to walk you through other then what I have mentioned, that it is getting power and cord is good. Please keep me posted.

Rinnai Energysaver 1001F - Turn on, ignites, blows + powers off

Try disconnecting the unit and thoroughly cleaning the dual walled intake and vent pipe that goes through the wall. Use a small brush to make sure the passages are free from any obstructions. These units have safety mechanisms that are very sensitive and sometimes will shut off when something as seemingly insignificant as a leaf or spider web creates a slight blockage. A yearly inspection and clean out are necessary.

Absolutely no power to my Lasko 5540 heater

There is a thermal fuse in line with the power chord. Open your heater housing up and trace the power cord. It is located inside a white teflon sleeve. Locate the fuse and either replace it with the same value. Appliance repair shops will have them in stock. If you want heat right away, cut out the fuse and jumper the 2 wires together. Instant heat.

Convection Heater Light on Knob HBH 5015

It is normal for small orange neon indicator lamps to blink or flicker when they're about to burn out. This should not be a problem unless you notice other electrical problems such as sparks or smoke.

Any easy test for electrical problems in your heater is to turn on an AM radio in the same room with the heater...and tune it to a clear station that you can hear clearly. If you hear steady crackling sounds or static in the radio while the heater is on, then the heater should be inspected for electrical problems.

Heater is getting power, but will not work

I guess of heater element are open and this can cause the fan from not working because both of them are on the same wiring
