Replacement for Ultimate tube heater fan?

[slash007]

There are a few threads about replacing the fan on an Ultimate tube heater, but they are old. Has anyone found a direct or compatible replacement for the fan on the tube heater? I had tried calling Ultimate, but it seems they are closed all week or maybe forever since their voicemail doesn't indicate anything, but if I could get a local replacement to expedite the process and save money it would be great.

Thanks.

Of course after I post this they finally answer.... Anyhow, they don't sell the stainless version anymore and want $275 for the steel version without the inlet even included.

Found it on Zoro, here is the item #G2103403. Grainger has it as well, but of course it costs more there. I paid $81 after tax, Ultimate wanted $275+ shipping.

Anyone by chance know of a replacement for the pressure switch? Replaced the fan, but seems the pressure switch might be defective as well. Wondering if this one would work: https://www.zoro.com/cleveland-controls-air-sensing-switch-adjustable-ns2-0000-05/i/G0400994/ Thanks.

Slash007,

If you can find out what the pressure range & the differential range is for a known working heater, then you could be more sure on whether that one you linked to would work. For our modular pulse boiler system & our washing machine water level pressure switches ... using the proper range Dwyer Magnelic is great for testing & tweaking the adjustment screws in needed. http://www.dwyer-inst.com/Product/Pressure/DifferentialPressure/Gages/

View attachment 1055 Here is a picture of the current pressure switch. The one I linked has an adjustable range from 0.10 to 10.0, so that part should be fine as the original is .56. I am still not sure if the pressure switch is the issue. Shouldn't I be able to bypass it and confirm? All 3 legs are used, so I wasn't sure what two I need to jump together in order to bypass the air activation.

When the pressure builds up it should make or break contacts. Hopefully, there is not anything else that would complicate the testing with a simple continuity check on even the most basic multimeter.

My believe my ultimate heater uses a c-form contact. It looks for a closed and open state depending if the fan is running or not. I had trouble with the pressure switch not operating correctly and ran a wire through the little hole where the hose connects on the heater and cured my problem. I think it started to corrode shut.

I just picked up a universal one from a local shop and it worked fine. I left it set at the minimum rating of .20. Zoro has them for around $13, so those should work too if you can wait for one. https://www.zoro.com/cleveland-controls-air-sensing-switch-adjustable-ns2-0000-05/i/G0400994/
