Question about Sanyo Heating & Cooling
If it is new split air conditioner with a four way valve and it stops giving heat. Check if there is any power going to the coil of the four-way valve. Check also the continuity of the coil. If there is power and the continuity, replace the four-way valve. If you don't get power going to the coil, check the wiring. If wiring is good, replace the electronic control board.

Did you check your coolant level or was it low and you added to it at some point? If so the system my need to be bleed or worst case the thermostat is going bad.

Gas valve coils
Watch the igniter. Does it glow bright orange, then shut off without igniting the gas? (When the gas ignites there's a large blue flame.) If so, there may be defective coils on the gas valve. Mounted on the top of modern gas valves, there are black electrical coils. The coils, when energized, open the gas valve. If one or more of the coils are defective, the valve doesn't open and the gas cannot ignite. Because it's often difficult to properly test the coils, it's usually best to replace both (all) of them at the same time.
I hope this helps....

This unit is use in motels etc. Check the ouside coil ( conderser) from the inside (discharge fan ) for dirt. Most of these units are floor level . This can cause a unit to short cycle ( cold air is at the floor) .

With your front heat working the most likely cause for the rear heat not to work is that there is an obstruction in the line that is preventing the warm coolant to get to the rear heater core or the rear heater core itself is plugged and not circulating. Another possible cause could be low coolant level where the system has enough coolant to provide the front system with enought warm coolant but not the rear system. Hope this helps
