Where is the "Manual Heater Reset Switch" on an Amana PTH093B35AJ? Unit has good A/C but no heat at all. All components test good.

The manual reset is a small switch on the computer control board. If that doesn't fix the problem, while you are there, you will see 2 small black boxes wired into the computer board marked "heater 1" and "heater 2". These are relays, one of which has probably gone bad. You can either order a computer board for about $100 or replace the relays yourself with a soldering gun. You can order the relays for $4.02 apiece from Digi-key Corp. Part # is JTN1aS-PA-F-DC5V for the relay.

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'm seeing a master switch on the control board, try a reset there. But, sounds like a bad element. You need to test continuity through your heater components. When testing a component unhook wires first, as they will still have continuity even if bad with wires attached.

First unplug the unit......Take the front cover off, take the wire screen off where the front fan is there is 4 or 5 screws that hold the plate that was under the screen. The electric heating elements are under that plate between the evaporator coil and the front blower wheel. It will lift straight up and give you access to the elements. In the electric heating element area there is a limit switch with a red or black button in the center of it push it to reset the limit it is on the right hand side by the controls. I wish I could find a picture to show you but I couldn't find one. It is not easy to get to... Hope this helps.

I don't think the Amana ASZ14 Heat Pump has a reset switch, but you can still reset it by resetting the power (when it's not running... turn your thermostat OFF first).

To reset the power, locate your circuit breaker box. There should be a double-breaker for the Heat Pump and another double-breaker for the Air Handler. Turn them both off for at least 2-3 minutes. Then flip them back on and turn your thermostat back ON.

You're thermostat may also have a RESET button that you can push. I have to reset mine every time I change the batteries in it.

I have the same problem, and I found the manual reset inside the unit. Turn the power off, and unplug the unit. Remove the outer cover of the unit ( inside cover ) , and remove the 2 screws holding the " wire mesh " in the front of the cover. Pull the wire mesh up and out of the way, then carefully pull out the heating element.
On the heating element, where the wires are connected, there is a manual reset button... Push the button in, till it resets...

My reset was on the upper left connection of the wires... just looks like a small push button, but the reset is recessed a bit.
Replace all covers and plug back in.. working fine..

I dont know about this model but in general electric heat wont have a reset button the heat is controled by a sequencer and each elememt has a safty limit switch incase the sequencer sticks in the on mode here is a link to where you can get more info on this model http://www.fixya.com/support/p51773-amana_ptc153b35aj_air_conditioner

when is it the last time you cleaned the unit and changed the filters? it may be working good but you need to maintain the unit...clean all filters and see if you can vacum alll parts especially the condensing unit (you may need air pressure) can you move the unit to outside so you can clean it good? if you can use air or water pressur to clean it after you cover the lectrical parts. Good luck. (save your money this unit need cleaning only)

Sounds as though the power cord reset switch might be bad and need to be replaced. If not, then there is a short somewhere in the system. Do an ohms test on the switch to determine if it is bad.

The reset button is located behing a panel on the front of the unit that is labeled Heat Reset. If that label is gone then look around, it is a small hole, small enough for a paper clip to fit through.
That being said, I have 137 of these units in one of my hotels and have not had a single one needing to be reset. You probably are going to need a new control board kit. These can be purchased from Amana. They are $130. Make sure that you have pulled the heater coil out and inspected it first. Also, there was a recall years ago where Amana was supposed to contact and send out new voltage switches. These are the round black things that the Brown heater wires connect to on the upper and lower side of the heating coil. You should also try to replace those if you find the coil in good condition. I have had those resolve heating issues. Most of the heating issues were a result of a bad relay on the control board though.
Please remember to rate this fix.
