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.

Re: Heater is getting power, but will not work

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

Re: 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

What are the chances my 7101 will still work after sitting in 16 inches of water for 6 hours? Leery of plugging it in.

Wash it thoroughly, open the electrical boxes and wash them with pressurized water to wash away the silts. Dry it with a hair dryer set on low heat. Don't get the things too hot to melt anything. When dry, close the electrical compartments. Let the radiator sit for about 5 days. Putting it under the sun will help for the first day. Try it after 5 to 7 days. It usually works just fine.

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.

Heater used once 3 yrs ago. Now wont start.

When the heater hums is the fan turning. If it is I would add more Kerosene. There is no shut off but the Kerosene is sucked out a tube from the top of the tank. This tube does not reach quite all the way to the bottom of the tank. Your heater should hold about 9 gallons if it is empty. A couple of gallons would give it plenty to run though. Let me know.

Lasko heater model 5620

Underneath the heater element are two thermostats that are run in series with each other. Inside the wire that connects them is a thermal fuse that opened up. Replacing the fuse corrected the problem.
