Suddenly in power outage and engine starts auto., NO inside power
9-3-09 -- A very recent problem with a 3 year old new house installation of 16kW Generac with 100A exterior transfer switch feeding seperate inside distribution box is, when power goes off, while the generator NG engine starts up automatically, no power in house. The transfer switch does NOT trip automatically as previously. When I trip manually with yellow lever, while engine continues to run, still NO electricity. Thruout this time, the green LED remains flashing "utility not sensed" AND the 65A circuit breaker on control panel in unit remains ON. All breakers have been switched on and off just to be sure OK. When main power is restored, generator shuts itself down in <60 secs. Problem continues when power outage is simulated by tripping main breaker. All oil, filter and plug changes faithfully made on yearly basis. Does it sound like transfer switch or controls or ? Your comments, please? ****

The problem with the repair service is another matter. Emergency generator and it's switch gear are there for emergency purposes. It has to be exercised periodically. The switch gear should have a toggle switch to simulate a power outage. the switch cuts power to the sensor sensing power from the utility company. This tells the switch gear that power was lost, start the engine and switch over to generator power. Run for a period where engine reached running temperature and switch back to stand by to shut down. Do this periodically, and be grateful the event was not a disaster. Think of your back up electrical system as the spare tire of your car and similar equipment and enjoy your investment. Good people brings you happiness, bad people brings you experience !.
your furnace uses 115 power & there is a transformer in this unit that powers the low voltage controls. i would say that when they replaced the board they missed some issues with the low voltage control wires. which is likely to be what cause the board to go bad. theses low voltage wires are the only thing that can tell the outside unit to come on. the lights dimming tells me that you have a bad capacitor or need a hard start kit. the lights normally only dim if the compressor doesnt start.
To install a thermostat on Your 1999 grand cherokee jeep. You will be needing these instruments, Container, Clamp tool or vise-grip pliers, Thermostat and gasket, 10mm socket or wrench, Razor blade, Flathead screwdriver (if necessary). Then You carefully follow the steps below:
Open drain **** on the radiator to drain the coolant from your Jeep Grand Cherokee. This drain **** is located on the lower right side facing the rear of your Cherokee. Use a seal able container and reuse the coolant if it is relatively new and clean.
Follow the upper radiator hose to the point where it meets the thermostat housing. The thermostat is located inside the housing. Use a clamp tool or vise-grip pliers to loosen the clamp holding the hose to the housing. Work the end of the radiator hose free of the thermostat housing.
Remove two bolts holding on the thermostat housing cover. Pull off the cover. Take note of the position of the old thermostat. Remove and install the new thermostat in exactly the same position.
Scrape off residue of the old thermostat gasket from the inside of the thermostat housing cover using a razor blade. Avoid getting any debris inside the thermostat housing.
Install the new gasket. Reattach the thermostat housing cover and radiator hose. Start your Jeep Cherokee and run the heater on high. Allow the engine to warm up. Check for leaks.
Those are the steps to follow to install your thermostat. Hope this was helpful. Thank You for using fixya!!!
Mines, two or three years old and doing the exact same thing, you ever figure out what happen or how to fix it? I took the battery out and it reads 16 volts. I put a 2 amp load (fan) on it and it pulls fine, so I'm reluctant to buy a new battery pack for it now.
I install and work on these everyday. If you hooked up the transfer switch you probable have a control wire wrong. check the utility power sense wire. That lets it no when to start in auto. it could be a relay or fuses. or a control board.
I got mine in 2005. It stopped working 4 or 5 weeks ago. It made a clicking noise and the compressor was very hot. Compressor is under warranty but appliance repair shop wanted $125 to install it and another $75 to charge it with freon. I saw a posting somewhere else that said it was a relay switch. I ordered one from RepairClinic.com for $24.00 incl. shipping, put it in and it's working now. There's a black plastic housing on the left side of the compressor. Just unscrew that, pop the cover off (that was a little tricky) and plug in the new part. Maybe I'll get another 3 years out of it.
