Heater is getting power, but will not work

I have had the heater for 16 days and it stopped working 5 days ago. The power light will come on, but it will not heat and the fan will not come on. I have attempted to reset it several times and tried it in several different outlets.

Sorry about the length of time, but I just found this website.

My wife bought 3 of these when it became apparent that our oil furnace needed to be replaced. One crashed, as did yours. The neon lamp lit, indicating that the unit was receiving power, but neither the heatin, nor the fan worked.

We got a new furnace. I just took a look at this near-garbage that was in my workshop. I trouble-shot it to an internal fuse that has obviously blown. I went on this website hoping that someone had the fue\se rating so that I can replace it.

The unit is a little tricky to open, but, pretty much, just open (and save) all of the tiny screws (except those in the feet - not necessary), including those that secure the side brackets. (The unit folds together, and you can't fully get it apart without, somewhat, "unfolding" it.

Good Luck

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

    That means there are 2 set of wiring 1 for the indicator lamp and another for the heater and fan.You have to open to see it.Make sure that it is not connected to the main supply.A simple continuity test will give you the result

Cozy gas wall heater won't ignite, pilot light is on


There are two types of igniters, spark-type or glow heater. The glow heaters wear out and crack or break and the spark-type spark gap gets fouled or dirty. Both could have electronics problems that drive the glow heater or spark systems. The Filtrete thermostat is not the issue. While rapping the unit makes the glow igniter come back together to glow again.

I have a Nortitz natural gas water heater, model #N-063s-1. Acouple of days ago it stopped heating the water. what can I do myself to fix this matter. Thanks, lynnatheana@hotmail.com


There are many reasons a tankless heater will stop heating water. The first thing I would look for is a flashing red light on the burner indicator. The flash break down goes as follows

continuous blinking - typically means ignition failure or the unit is overheating; look for visible water inside the unit, have your gas pressure checked, or check the flame rod/igniter for buildup of debris

three blinks - typically indicates 16 error code; typically resolved by performing a descale

4 or 5 blinks - exotic error codes; for these you should definitely contact Noritz tech support

If there is no flashing light, first check your filter for debris. If the filter is clean, your flow sensor is probably stuck. Again I'd recommend contacting Noritz tech support to help you clean the flow sensor.

If the Aqualink is calling for heat then the problem is most likley in the heater. Without more information I can't tell you much more but if nothing has changed in the last couple of days. Before you call anyone be sure to clean your filter and baskets. The heater need a set amount of pressure to run and if things are dirty it won't get that pressure. Good luck.
