Question about Procom NetFORCE 1750 (NF-1750) Hard Drive Array

1 Answer

Unit keeps powering down every 15 minutes

Hi, Our NF1750 keeps powering down every 15 minutes or so. The Procom software doesn't detect the fan spinning on the processor, even though the fan IS spinning. Switching to the other processor slot has been tried as well to no avail. Has anyone had an experience with this? Is it a motherboard failure or something else? thanks

Check the internal sensors. There were 2 of them that sensed the internal temp of the system. the one in front sometimes would break. Those units also had a smart card that did all the montoring. Its the only isa card in the system. It can cause these weird problems.

It keeps going through a start up process (clicking and the fan come on then off quickly) at first staying steady then getting longer in the start up process.


Hi David, thank you for your inquiry. I understand that your Frigidaire Refrigerator is cycling on and off more than you expected. Todays newer refrigerator's have to meet Dept of Energy (DOE) specifications for energy savings. Typically the fan and compressor runs to get the fresh food temp down to 34*, the compressor shuts off and the fan runs for thirty more minutes and shuts down. The fan will repeatedly cycle on and off to keep the temp down as close to 34*. Once the temp in the fresh food hits 40* for more than two minutes the compressor cycles back on again. This will cause the temps in the fresh food to dwell between 35-40 and in the freezer section between 8-15. Hope this helps! -JK

How do I resync my ProCom remote with my ProCom Vent Free Fireplace? I have an older model, SSU320RHL-GB.


I ran into this same problem yesterday while I was trying to get my used unit up and functioning.

If you don't switch from pilot to off and wait about a minute before turning it to the "electric" mode, the remote will NOT light the unit.

Ventless wall heater shuts off during operation


Sounds like thermostat may have a battery going bad as to not supply sufficient power to turn on the relays. As safety procaution when a signal is weak or no longer detected the heater shuts down.

if you haven't tried this,unplug the power or shut the circuit breaker off for 15 minutes,this may reset the defaults on the unit,if this doesn't help,then shut off power to the unit and open up unit and disconnect each and every connector to check for poor conduction,then reconnect power,if this doesn't help then replace the c.c.u. central control unit

Cooling doesn't stay on


The outside and inside coils may need cleaning. Clogged coils cause excess pressures and heat of the freon that can cause safety switches to shut er down. Eveen a faulty power relay in the outside unit.Otherwise you may need a serviceman to locate the cause.

The 15 min timer doesn`t work anymore tried getting a new switch and still nothing. Any suggestion?


Fan or electrical wiring or power source are suspect.

Fantek RTS2 is supposed to boost HRV/ERV system into high speed for 15 minutes.
http://www.iaqsource.com/category.php/fantech-ervs-and-hrvs/?category=1494

If new RTS2 is not working, then either the wire to HRV/ERV system is suspect, unit is not getting power, or the HRV/ERV system is suspect.
If you are using RTS2 for ordinary ceiling fan, then install regular on-off switch and see it that works.
Check that you are getting power to switch and to fan. Check circuit breaker.

Unit shuts itself off after 10 -15 minutes


Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.
