Bosch TF250 Not Heating up

There is propane gas coming in but not going out the solenoid the contacts are very dark it doesnt close to allow gas through, Batteries are new plenty of HV spark but no gas to ignite. Running the water still doesnt move that closing, the voltage across the solenoid is very very low if anything. Don't know what to think solenoid or HV might need replacing, There was a lot  green around the negative terminals of the batteries  cleaned that, will need new battery contacts after the oxide gets to it, who knows.

Is something blocking the gas to go in to the solenoid check that first.

    there is a sensor that goes from the gas valve to the pilot that is called a themocouple, change that and it will mostly solve your problem of not heatimg up.

    there may be a loose connection on the downstairs thermostat mounting plate ensure all power is off and check that all connections on the mounting plate and the pins that contact the controller are in good order.

    When a refrigerant is compressed it still contains the same amount of heat energy (don't confuse that with temperature, that's something else altoghether) that it had BEFORE it was compressed and since the volume is smaller, the temperature goes up. The state change (gas to liquid) also gives off a lot of heat, but don't let that part confuse you. The compressed (and heated) refrigerant is then passed through a coil of tubing and the heated refrigerant is cooled by the ambient air completing the gas to liquid state change.
    Then the compressed refrigerant passes through an orfice (a restriction in the tube) and is allowed to "flash" back to a gas. Now it's at a much lower pressure and the volume of refrigerant now contains much less heat (again, not to be confused with temperature) that it did when it was a liquid. Another part of the process is referred to as the "heat of vaporization", which really cools things off, sort of like the cooling from sweat when you get hot

    There is either a problem with the downstairs thermostat, or the wiring from that thermostat to the unit. First check the batteries in the thermostat. Yes the digital ones have batteries. :-) Next, if that doesn;t fix it, try switching your two thermostats. Be careful to wire them exactly as they were before. If your heat now works downstairs and not upstairs, replace the thermostat. If the problem remains unchanged and you still have heat up and not down - check your thermostat wiring. The voltage is low so a simple voltmeter can be used to confirm continuity from the end where it goes into the furnace to the end where it connects to the thermostat.

    replace the blower motor and flush the heater coil. I know the vents are working properly because they work when the temperature is selected to cold. I am wondering if there is something under the hood that redirects the aif flow either through the cooling coil or the heater coil based on the position of the temperature control. If so possibly the heater coil (air side) is clogged. I noticed that the heater coil is below the AC coil so it is possible that debris is down in it. I may try to pull it and clean it. Have you tried that?

Rinnai Energy saver 1001f not kicking back on

I would suggest that your landlord is responsible for heating as you rent and must ensure the heating works properly, especially when using gas.
Contanct a Rinna service agent and have it serviced at your landlords expense.

I have a Dearborn heater propane will not light worked fine last winter had lines tape off model DRC303

Propane and natural gas heaters have standing pilot ignition or electronic ignition. If you have a standing pilot ignition you should see if the pilot light stays on when lit and after the valve is turned to the full ON position after lighting. Electronic ignition should light the pilot for you and then the burner comes on - but at the end of the cycle the pilot and the burner go off. If you do not have ignition, check the gas pressure -- 5-7 inches of water column for natural gas and 11-15 inches of water column for propane. Use the pressure noted on the regulator or other labeling. If you cannot test the pressure then contact your gas company or propane supplier for service.

We are now on propane instead of natural gas. we have a bosch gas dryer & we need this propane conversion kit installed. who would we contact for this ?

if you are looking to buy a conversion kit for your dryer -- I would just go to your local appliance store, they should have everything that you need, and if they don't I am sure that they can order for you what you need to make it work. ( make sure you give them the make and model of your unit ).

My refilled 60 # propane tank leaked and then stopped flowing.

Rick, if the tank is normally plumbed for a horizontal position, and you have it standing vertically, then you are feeding liquid propane to your pilot light, hence the frosted hose etc., and a tendency for the pilot light to go out as it has too rich of a fuel to burn. There should be no vent to allow air in as propane is pressurized, and only attains zero pressure at 40 below zero farenheit. The valve you speak of should have been the liquid vent valve which is used during filling only, and is closed during any other use. Your supply valve should be in the wide open position. The pressure relief valve is only operational when the tank has been overfilled or overheated. You should have a pressure regulator between the tank and the appliance you are trying operate. Hope this helped. Marvin

I received a Gas heating system from my dad and would like to know if I can switch it from Natural to propane gas. my model # RFN28TA.

Most furnaces come from the factory set for natural gas. If you contact the manufacturer to find the local distributor for that particular unit . you should be able to order a propane conversion kit. The kits are very easy for a trained heating guy to convert. A good handy man should be cable to do this changeover. BUT the manometer that is needed to properly calibrate the gas valve is not worth the purchase price for one application. I recommend that you use a trained heating guy.

Bosch dryer not heating

make sure you try it a couple of times. gas takes a long time to travel to the pipes. no way to purge the lines.

check if there is propane in the new tank, check if the valve is open, check if the propane is at the hose going to the dryer already.

tnx 4 using fixya,
