Old solution from a forum but it get sense.
Citation: "It seems like there could be several possibilities:
1. Refrigerator is struggling to keep cool - maybe because of high outside temp, maybe bad seals, maybe other issues. Fan runs all the time because the back of the frig is hot.
2. Refrigerator is cooling ok, but fan runs all the time because there's poor ventilation on the back - maybe vents are blocked in some way.
3. Refrigerator is cooling ok, but fan runs all the time because it has a defective or improperly adjusted ventilation thermostat (that controls the fan).
4. Refrigerator is cooling ok, but fan runs all the time because Dometic did not include a thermostatic control on this model.
I'd suggest checking the manual or calling Dometic to ask about #4. If there is a thermostat controlling the fan, it may be covered under the Dometic warranty (which might be longer than 1 year)."
If it's an older forced air unit furnace, it's likely the inducer motor has malfunctioned. They usually make a lot of noise before they fail, but occasionally they just stop working without warning.
Yes, most likely the start capacitor has failed & should be replaced. You have proven this by being able to hand-start the fan. Once replaced, the compressor should kick in & work fine.
Turn power off to indoor unit. Remove red, yellow and green wires from tstat and wire nut the three together. Turn power to indoor unit back on. This should bring on indoor fan and outdoor conpressor and fan. Let me know
The fan on that vehicle is turned on by the engine computor. There are also at least two, maybe three relays for the cooling fans, and they are marked on the lid of the underhood fuse block. The fan thermostat you are looking for is the engine coolant temperature sensor. If your temp gauge is reading correctly, this is probably not your problem. Also when temps sensors go bad, the engine usually runs very poorly. These vehicles did have durability problems with the cooling fan motors themselves.
no it is not normal....have a repair shop check the coolant fan sending unit or the coolant fan relay...a bad sending unit maybe sending a false overheating signal to the fan causeing it to stay on or the on off fan relay maybe sticking on..an make sure the jeep is not actually running hot the temp guage maybe reading the wrong temp
The thermostat was just replaced and it still does the same thing.
Is it correct to assume that the usit should not run when the thermostat is turned off?
