Question about Geospring Hybrid 50 Gallon Heat Pump Electric Hot Water Heater - EnerStar
Model GEH50DNSRSA lightly used. Picked this up figuring I may be able to fix, and in hooking it up the panel display says"incorrect voltage of 120, correct wiring to 240" or heat pump error. There are no errors in the diagnostic menu and voltage is good. I did find according to the wring diagram, that from the factory the blue and yellow wires were switched at compressor for heat pump. Figure this may have done damage to board possibly.

Most of the cases when tou heard a click on and off is aproblem with the compresor that goes off on overload, when the compresor try to start and is stuck , burned or the starting coil inside it is open it's overheat and goes off by the thermo bimetal switch.Also could be the capacitor, to check it you need a capacitor tester,but if you don't have it you can try to put anew one (no more than 10 $) and see what happend if still the compresor is getting hot and won't turn on it's burned, jamed or open , and you have to replce it ,if it's less than a year old it should be under warranty but if not is an expensive job and you better get a new unit.

If it was me I would cnage the sensor first. Simply because it is way cheaper than the control board and these sensors are fickle as hell to begin with.

Those terminals on a ductless split are reserved for the communication wires from the out door to indoor unit. L L N should be line 1, line 2, and neutral (ground) there should be a 1 2 3 N terminal block in the indoor unit also, those terminals would most likely be for the communication between the two units.

Standard hook up for Heat pump.
White--------------W1 with a jumper to E sometimes will also say Aux, varies with Manif. of T-stat.
Hope this helps you out.

PROBLEM #1 - HOT SURFACE IGNITOR DOES NOT GLOW RED
(Remember to wait for purge time, 17/34 seconds, on models so equipped).
A. No main power
B. Faulty transformer
C. Faulty thermostat
D. Faulty limit switch
E. Faulty blower interlock switch
F. Faulty hot surface ignitor
G. Faulty ignition control
Perform normal system checks of main power, transformer, thermostat, limit
switch, blower interlock switch, and replace faulty component.
With power on and thermostat set at its highest position, check voltage
between "TH" and "TR" on HS780 ignition control. If 24 volts is not present
check output at transformer. If no, replace transformer. If transformer
checks out OK look at other controls in the 24 volt circuit I.E.: thermostat,
limit switch, blower interlock switch. Check for 120 volts between "neut"
(L2) and "120" (L1). Check for 120 volts at the ignitor across "IGN" and
"IGN" terminals on the HS780 ignition module. If 120 volts is present,
replace ignitor. If no, replace the 780 series module
PROBLEM #2 - IGNITOR GLOWS RED BUT MAIN BURNER
A. Improper ignitor alignment
B. Faulty ignition control
C. Faulty gas valve
D. High inlet gas pressure
E. Polarity reversed
F. No earth ground
Check for availability of gas at gas valve. Make sure the manual valve
upstream of the gas valve and the gas valve are in the full on position. Also
make sure gas is being supplied to the system at the proper pressure, too
high will lock-up the valve.
Check proper polarity of "NEUT" and "120" on the ignition control by reversing
the wires, if reversed gas valve will not open. If this does not solve the
problem, replace wires as they were.
Check for proper ignitor position.
Check for a good earth ground by using a meter connected between L1
and furnace chassis. Should read 120 volts, if no, check and/or repair ignition
ground wire or ignition control mounting screws.
CAUTION POLARITY MUST BE OBSERVED
Check for 24 volts at the gas valve terminals; "1" and "2" on a 7200 series,
"M" and "C" on a 7100 series, "TH" and "TR" on a 7000 series. If yes,
check wire integrity or change the gas valve. If no, change the 780 series
That is pretty much all of the troubleshooting required.
Thanks for choosing FixYa,
