Question about Fahrenheat FFH1615 Heater

2 Answers

Low air flow

Ever since new, the fan doesn't move much air, the heat doesn't blow out quickly, the bathroom takes a long time to warm.  Is this common with this heater or did I just get a dud, would a different brand move more air?

Re: low air flow

Most fan forced wall heaters do not move a lot of air. check the cfm rating on the heater. the fan sucks in air from the bottom and forces it up to the top where the element is. broan and nutone have good air flow.

Blows only warm air, not hot

Many of these heaters have four infrared heating bulbs inside, and they do burn out over time, and it doesn't put out as much heat. If you take off the outer case (usually 4 screws hold it on) you'll see the bulbs and will be able to determine which ones are not lit up and need replacement.

I have a york diamond 80 heater. The part that blows the heat out won't come on.. igniter lites and flames come on but blower doesn' we are freezing

Sounds like your fan switch is defectiveor posibble installed in the wrong place. This switch is heat controlled and delays the fan coming on until there is warm air to blow.

Keep shutting off

I would be careful with a electric heater. The fan must not be moving the heat from the elements. Low air flow. It sounds like it is going out on high limit. Please unplug and do not use. You may need a new fan. It would be cheaper purchasing a new heater.

Hope this helped you...Jim

Blows out cold air at times


In their effort to try to boost the efficiency of the heating units the fan sometimes runs even when the air will feel really cool...

The fan may start up before the heat exchanger is warm and may run after the heat exchanger has cooled off...

Probably nothing wrong... just the way it is...

Heater works, but only on Emergency Mode

It sounds like you have a "setback thermostat" A control intended to increase efficiency by allowing the fan to run for an adjustable amount of time after the heater turns off, whether the heater is electric or part of a heat pump. If the "setback" time is too long, the element will cool off and the fan will blow cold air. Try and locate the instructions for the thermostat and see if the "fan run time after heat turn off" is adjustable and reduce it by half. Most emergency heat circuits bypass control circuits (its an emergency, you know), and require manual control.

My heil heat pump is not blowing warm or hot air

Assuming that the fan is okey, there's only one item to be checked, and that is the HEATING ELEMENT.
This answer is based from your comment that it is not blowing warm or hot air. So, I conclude that it is blowing air but neither hot or warm, only ambient air. So, unplug it, and check the heating element. It may need to be replaced to make it work. May this will
help you.

Air from the heater is not really warm.

Have you changed your air filter lately?

Gas heater doesn't stay on longer than 5 minutes.

It sounds to me that your air flow is restricted somewhere. The first thing to check is your air filter. If that gets real dirty your restricted air flow will cause the hi-limit(hi temperature limit switch) in your heat exchanger compartment to over heat and open up your gas valve electrical circuit,thus, shutting off the gas to your burners. After the hi-limit switch cools down the furnace will go back to heating again then it will overheat again(you get the picture?) If it keeps cycling on and off like that the house will never get warm if it is cold outside. If your air filter is reasonably clean(you should be able to see light thru it easily) then the secondary heat exchanger could also be dirty, this is located above the indoor fan housing, you would need to pull the indoor blower assembly out of the furnace and look up above. The secondary heat exchanger looks similar to a radiator will fins. You can use a medium stiff plastic brush to brush the dirt,hair, whatever off of it. Another problem spot would be the cooling evaporator coil (if you have central airconditioning) located most likely above the furnace in the plenum(if your furnace is in a basement). This usually is difficult to access if an access cover wasn't installed when the airconditioning was installed. I would recommend an experience service tech to clean it for you. Also make sure all you supply air registers and return air registers are open . These are the things I would check first. Good luck!!

Heater comes on but quickly over heats.

There is no Filter On this Model. Check to make sure there is Dirt in the Flow way of the two towers. if that is not it the back up fuse in the heater is going bad.
