From Rabbi Dovid Ribiat's The 39 Melochos (p. 378): a) Aerosol spray cans ... The Igros Moshe permits the use of aerosol cans on Shabbos because the scattering is not caused directly by blowing or wind-force, but rather by the pressure of the liquid as it is forced through the microconduits in the nozzle head. Since the scattering is not ...

Your question is exactly that asked by Rabbi Cohen over at Dose of Halacha. He asks "Can I use a timer on my hotplate to heat my chicken on Shabbos for lunch?" While one mustn’t place a davar lach, a boiled food with liquid on the stove or hotplate on Shabbos, R’ Ovadia Yosef (Yabia Omer 10 OC:26) allows one to place such a pot on the hotplate while ...

The problem is that the stove top on Pesach can make your pots chametz much more easily than it could make your pots non-kosher during the year. As a result, even splash back or resting the pot on the stove top could cause problems. Also, the splashback from the stove top could cause your grates (on which the pots rest) to become chometz. This then affects ...

If you need the food in the fridge and there's no way to take it out b/c it will spoil, then just leave the fridge slightly open. If that will cause the food to spoil, then you can use a non-Jew to (repeatedly) ...

ילקוט יוסף קצוש"ע אורח חיים סימן שכב - דין נולד בשבת ה. מותר לעשות מי - סודה בשבת על - ידי הכלי המיוחד לכך שנקרא "סיפולקוס" או "סודה סטרים", ואין בזה שום חשש לא של עובדין דחול, ולא משום נולד, ולא משום מכה בפטיש. ובלבד שיעשה זאת לצורך השבת. ואם הותיר לאחר השבת אין בכך כלום. [ילקוט יוסף שבת כרך ג' עמוד תי]. Chacham Ovadia allowed this as well.
