Question about Reddy R155D Utility Heater

1 Answer

Blowing smoke immediately prior to auto-shut-off

Our heater works fine, except just before it goes into it's high temp auto shut off function, it starts billowing out white smoke.

Is this a problem with the auto shut off not turning off the fan and fuel supply?

it turns the fire off, but the fan and the fuel are still blowing ( hence, the white billowing smoke)

isn't there a multi switch that should shut all three off?

Try a new CAD falme sensor, or high limit control, both very cheap.

My Miller furnace occasionally stops in mid


If the flame looks good prior to the room air blower starting but becomes unstable when the blower starts, you have a crack or hole in the heat exchanger. I strongly suggest your technician do a test on it to see.

My pilot is lit.the gas is on and my thermostat is fine,but the furnace will not ignite. Thanks


Don't know your furnace model specifics but if it has a powered exhaust blower it must be blowing and the pressure/vacuum switch must be functioning.

Also if you had a malfunction and the high temp or out of burner flame detectors tripped you will need to replace them or manually reset them depending on type to get things back up and running.

Also most furnaces have a safety switch on the blower cabinet door and will not let anything start up if it is not made..had it happen to me loose panel on furnace shut it all down.

Heater shuts off as soon as the room is warm


I take it once the temp is set to 71, and the ambient temp reaches 68 or so, it shuts off, never to come on again?

If that is true the thermostat in the unit is damaged, worn out or in need or replacement, but try a couple tricks.

First, if there are access panels to clean, clean it per the manual, it could be that a dirty filter or air inlet is confusing the thermostat.

Next, unplug the unit for at least 5 minutes, try it again.

Next set the unit on it's highest temp and blower setting, let it rip for 20 minutes, shut it down, unplug and remain unplugged for 5 minutes.

Next set the unit at 71 HIGH MODE.

see if we have a mode switch problem or thermostat if it works on high mode, it is not the thermostat, but I imagine it is, but I am curious as to if it once goes off, it never again comes back on?

Vornado heater doesn't work on high setting but only at low setting


Dust on the inside of the unit can cause the overload switch to shut many vornados down. Blowing the dust out of the unit with compressed air or a blower may help.

Another problem that causes vornados to stop working (light on - no heat no fan) is when one of the bearings starts to go bad in the unit. This causes the fan to be slower and less effective and the unit’s inability to move the heat away from the thermal overload switch again causes it to shut down.

Though you could remove the front and rear bearings and try to get replacements if it's even replaceable ... Once the bearing starts to go bad there is little that can be done ... HOWEVER, here is one solution to get more life out of the unit.

First, use a blower to blow all the dust out of the unit.
Then, because it is typically the front bearing that goes bad first, lay the vornado on it’s back (so the unit would be blowing air up toward the ceiling), this will relieve the front bearing somewhat and rely more on the rear bearing which tends to last longer.

The vornados I’ve had are all thermistor units ... that is, they don’t just turn on and off when the set temp is reached but in fact slow themselves down (both heat and fan) to keep some level of air circulation in the room. This is a good thing by the way.
There are usually two toggle switches .... one is a heat switch - usually Low & High .... the other is the thermistor switch (this sometimes is labeled “fan”) - usually Auto & High.

Once the unit is on its back ... Now, change the settings as follows:
Turn the Heat switch to LOW
Turn the Fan switch to HIGH
Turn the dial (with the temperature in degrees on it) to the lowest setting - which is somewhere around 60’ish.

Now turn the unit on and it should stay working.
Three things that could cause it to turn back off ...
You turn the Fan switch back to Auto.
You turn the Heat switch back to High
You turn the temperature selection dial too high ... though, you can cautiously turn the dial up a few degrees at a time ... the unit will start shutting down again when you set the temp too high ... then just dial it back down ... unplug for a couple minutes, then turn back on.

Honeywell HZ-705.....HELP!!!!


Should have oil in it. I don't think you can refill it. If it has leaked out, it's probably no good. Anyway, here are the instructions.


Press the *power button* once to start the heater on high power, continuous run. If left at this setting, the unit will run continuously on high power (1500 watts, 12.5 amps) and will not shut off until the unit is manually turned off.
Press the *power button* again, to change to low power, continuous run, (900 watts, 7.5 amps) and will not shut off until the unit is manually turned off.

Set temperature:

Press the temp/timer button until the temperature icon blinks. Use the up and down arrows to set the desired temperature.
The temperature icon will stop blinking and the current room temperature will reappear after the desired temperature is set.

The heater will turn off and on to achieve the desired temperature.

Set timer: (auto off)

Press the timer/timer button until the timer icon blinks. The hour display will appear. The auto off icon will also appear.
Use the up and down arrow buttons to set the heater operation time between 1 and 10 hours. This function will activate once the timer icon stops blinking. The heater will automatically turn off whn the times runs out.

Set timer: (auto on)

Press the temp/timer button until the timer icon blinks. The hour display will appear. The auto on icon will also appear.
Use the up and down arrow buttons to set the heater start time between 1 and 10 hours. This function will activate once the timer icon stops blinking.
The heater will automatically turn on when time expires.

Hope this helps!

No Heat!


Sometimes too much dust around the heating elements can cause the heater to switch off to prevent a fire. Check for dust build up first. You can try using a can of compressed air that can be found at many electronic stores.
