Unit keeps powering down every 15 minutes

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

Common problems are faulty battery, or overheating due to faulty fan. If the machine shuts down when on mains power, listen carefully for the fan. If the fan is silent or slow , you could try using a vacuum cleaner to clear any fluff out of the fan unit or get hold of a laptop cooler tray. If the unit doesn't shut down on mains power, you should get the battery checked.

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.

Fan is probably not working.

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

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.

Fan or electrical wiring or power source are suspect.

Fantek RTS2 is supposed to boost HRV/ERV system into high speed for 15 minutes.

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.

either bad fan motor or dirty condenser coils need cleaned..possible obstrution with fan motor keeping it from turning.

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.
