Where is the Manual Heater Reset Switch on an Amana A/C and Heater Unit Model number PTH093B35AJ? The unit has several stickers that state it has a "Manual Heater Reset Switch".

Almost certainly it is a bad relay on the circuit board. Sometimes you can slap the side of the unit by the control box to temporarily unstick the relay, after which the heat will come on for a cycle or two. There are two relays on the circuit board marked "heater 1" and "heater 2". You can order a new circuit board for about $100 or replace the relays at $4 apiece (order online from Digi-Key, requires solder connections). Part number JTN1a-PA-F-DC5V.

I have a reddy heater 100000 btu model r100a. Everytime I plug it up I have to push the reset button. It comes on only for about 30sec. Then the reset will trip back off and it shut down. What could be...

Does the heater light up before it cuts off. If it does, then you need to first clean the flame sensor. It is a photo type sensor. Remove the top from the heater and the flame sensor is a black rubber boot close to the burner. You can clean it with a soft cloth or a cotton swab and some alcohol. If the heat isn't lighting up before the reset trips, with the top off, start the heater and check the igniter. If it is OK look for fuel spraying from the fuel nozzle. Watch out for the fan while the top is off and the heater is on. If fuel isn't spraying out, check the nozzle for clogs and check the fuel filter. Let me know if you need more help and please rate the answer.

Heater stopped working. Fan works, control panel diagnostic check reports no failure code. Placard on front of unit says heater unit has manual reset, I can't find a reset button or breaker for heater....

The front panel should be held in place by four screw at the corners or snap in place. Either remove screws or pull gently on top right corner to remove cover. You should see a red reset buttom type reset. Push it in to reset. Hope this helps. Thanks.

We have a sunbeam Low profile ECOSMART heater that is always shutting off. Is this normal? We did not get a manual when we purchased it last year.

If this heater has a thermostat, yes it will shut off when the temp is reacjed The area it senses ca vary depending on it's location. If you put it outside it may never shut off, but, in a room closed up it would almost cycle on and off.

My airconditioner is not heating up, its the first time we have had it on since sumer

Are talking about the actual heater in the air conditioner? If so, have have come across the heating element having a tripped breaker. Some are auto reset while others have to be manually reset. This is caused because of the radiant heat that is built up after the blower shuts down. Hope this helps.

Ductless heater shutting down

There is a small wiring harness that goes from the main board down to the sparker board at the very bottom of the heater. Disconnect this harness and reconnect making sure all pins and contacts make good connection. If it continues, replace the wire harness. Also make sure the outlet that the heater is plugged into is a grounded outlet. Stray voltage can interrupt the thinking of this unit.

If all connections are good and the unit is grounded, you are probably looking at replacing the sparker board. I do have these parts and would be more than happy to send them to you for a donation.
