Rheem classic ix missing high pressure switch

I just replaced the fan motor for the condenser. i was told that to make it restart i would need to reset the high pressure witch to make it turn on.
I can push in the contact and start the unit manually. I was told it was not starting by itself because the high pressure was triggreed. I have looked all over the unit for the switch to push it back in. Any suggestions on where this switch is located?

    Rheem Classic 4 ton - Pressure switch is not resetting. Shuts down the outside unit fan and compressor, does not trip the breaker, but the only way to get the outside unit back on is to reset by manually flip the electrical breaker. HVAC tech has checked the freon and the pressure and checked the circuit board to determine what is causing the problem. The tech keeps telling me that the only way to determine these type of intermittent problems, and to determine if there is a real pressure problems is for him to be there to check the pressure when the unit shuts down. This unit has been doing this since it was installed. The HVAC tech has also stated that he does not know if the problems is a faulty pressure switch, problem with the outside unit fan. He suggested an automatic pressure relay switch to force the unit back on. Help!

Our Rheem Classic Air Conditioner Unit keeps tripping the reset button or something and we have to run out and trip it. Well today it won't turn back on.


What's probably happened is that your outdoor unit has overheated due to a high pressure/high temp situation. The reset button at the base of the o.d. unit is a HIGH PRESSURE RESET. This safety is factory installed to prevent the unit from operating under an excessive(per design) pressure.
•The o.d. coil needs to be cleaned
•The o.d. fan motor needs to be replaced
•The run capacitor(s) at the o.d. unit need to be replaced
•There is a restriction in the refrigerant cycle
Its also possible that a component has faulted, along with a high pressure issue. 1 problem can cause another. The reset opening sometimes let's us know something is wrong and its time to repair the problem before it gets worse. Its hard to say what to do now. If it was still opening the pressure switch you could try washing the o.d. coil. Call a tech!

What is problem when fan motor on outdoor unit gets very hot and compressor will not restart?


Ur compressor depends on fan motor of ur condenser. Ur compressor undergoes Hi-pressure because ur fan not working properly

Ice machince is going max freeze cycle shut down


1. Possible cause. Water leak. Check purge valve, water curtain, sump, sump hose.
2. Air filters clogged. Clean air filters.
3. Dirty condenser. Clean condenser.
4. Restricted location, intake air to hot. Have machine moved.
5. Ice thickness sensor dirty or disconnected. Check ice thickness sensor probe.
6. Water distributor dirty. Remove and clean water distributor.
7. Inlet water valve leaks through during freeze cycle. Check water inlet valve.
8. Connected to hot water. Check for bleed through from missing check valve in building water supply.
9. Incomplete harvest. Check harvest system.
10.High pressure cut out opened. Check fan motor pressure control, check fan motor, check controller using test mode.
11. Fan motor pressure control open. Check fan pressure control.
12. Fan motor not turning. Check fan motor, check fan blade,check controller using test mode.
13.Water pump not pumping. Check pump motor,check controller using test mode.
14. Pump hose disconnected. Check hose.
15. Compressor not operating. check compressor contactor, check controller using test mode.
Check compressor start components, check PTCR resistance and temperature, check compressor voltage, check compressor windings.
16. Low refrigerant charge. Add some refrigerant and restart unit. If cycle time imporves, look for a leak.
17. Hot gas valve leaks through during freeze. Check hot gas valve for hot outlet during freeze.
18. Thermostatic expansion valve bulb loose. Check bulb.
19. Thermostatic expansion valve producing very low or high superheat. Check evaporator superheat, Change TXV if incorrect.
20. Compressor inefficent. Check compressor amp draw, if low and all else is correcy, change compressor.

Goodman heatpump fan runs, condenser wont start


Either the condenser fan has bad bearings, or it has a defective fan capacitor.
Turn off the breaker to the outside unit.
Spin the fan blade by hand.
If the fan blade spins easily and will spin a few revolutions with no problem the fan bearings are good.
If not, replace the fan motor due to bad bearings.
I am pretty sure you fan motor is bad because with a bad capacitor the fan motor will not get up to speed and may just sit and overheat.
I'm leaning toward a bad fan motor.

Mv450 scotsman high pressure


Check to make sure the condenser coil is clean, fan motor is running during freeze cycle. High Ambient temp, Ventilation, The higher the temperature entering the condenser coil the higher the head pressure. Fan motor failure, pressure switch failure. The cut out pressure varies 400, 450 or 500 PSIG. Water supply failure. not enough water running over the evaporator plate will cause high presser.

E3 Outdoor activation of high pressure switch

Condenser coil is dust blocked.-Clean it. Rpm of fan motor is less-Replace capacitor. If over charged gas- release some gas. Check for continuity for high pressure switch, if no continuity, replace high pressure switch.

Hi I have just got dimplex air conditioner gdc14rcssa it goes well for a while then come up with a error message E3 not sure why.


E3 Outdoor activation of high pressure switch due to over charged gas. and also due to less rpm of outdoor fan motor. High pressure due to non condensable gas. Remove all gas and flush out. Then vacumize and gas charge. If motor less rpm, replace capacitor or fan motor.

Check the draft inducer air switch ( vacuum diaphragm switch) If the switch is opening when the burner starts, you might have a blockage on air piping coming into the furnace. Also prime the condensate trap on the condensate drain from the combustion fan. Also check the gas pressure, if your gas pressure is dropping, the gas pressure switch will shut it down. If it's too high the moment it comes on could raise the pressure in the furnace dropping out the combustion fan proving switch.

Check the air filter, condensate drain lines for blockage and vent piping for a build-up of water. If nothing, you will be needing to replace the circuit board (hopefully under warranty).

Freezer is warm, not freezing at all, fans run


If the fans your talking about are in the refrigeration section, then the unit is not in defrost. The interior fans shut off during the defrost cycle.
There is a condenser fan motor in the machine section by the compressor. If it fails, the problem you described can occur.
If that fan motor is still, and the compressor is cool to the touch, then no power is getting to the refrigeration section.
Could be a bad thermostat, or the unit has tripped off on the high pressure safety switch. The high pressure switch can be one of 2 styles. Auto reset, which means it will try to restart the compressor when the pressures become normal. The other has a lock out feature that requires it be reset manually. If it goes out on the high pressure switch, once reset, check the condenser fan motor to make sure it is running and/or excessive dirt in the condenser, which must be blown out.
Other causes can be a total loss of refrigerant, or a compressor that won't run.
Short of a broken wire all items listed except for a dirty condensor and reset of the high pressure switch, require a decent knowledge of electrical, Knowledge in the use of a VOM meter and amp-probe, as well as a set of refrigeration gauges.
